Toto - Hold The Line (Official Music Video)

Flea market surprise!!!

As you probably know by now, the Flea Market Surprise epsiodes contain a bunch of components that I have aquired from the flea market.

Flea Market Surprise - because you never know what you will find there! This is what makes the visits to the Good Ol' Flea Market, worthwhile. Trust me, I know what I'm talking about :D I can quit anytime I want, I just choose not to!

The presentation is short and I usually let the pictures tell the story. This is what a FMS episode is all about.

Let's meet the stars of this episode!

1. AMD K6-2/500AFX - 500MHz
2. AMD Athlon 1200MHz - AXIA0124UPBW - A1200AMS3C
3. Intel Pentium 4 - 1.4GHZ S423 Willamette - SL4SC
4. 3dfx Voodoo 1 - Diamond Monster 3D PCI 4MB Rev. E
5. Protac Video Excel AG240D REV2.2 - Fastware Intel i740 Power 3D
6. MITSUMI CRMC-FX120T - CD-ROM 12x
7. Intel Pentium II 350MHz - SL2U4

Quite a line-up don't you think?

AMD K6-2/500AFX - 500MHz *** AMD Athlon 1200MHz - AXIA0124UPBW - A1200AMS3C *** Intel Pentium 4 - 1.4GHZ S423 Willamette - SL4SC

The CPUs have been cleaned, pins have been straightened and useless labels have been eliminated.

3dfx Voodoo 1 - Diamond Monster 3D PCI 4MB Rev. E

A common card but illusive at the same time.

I paid for it, a little over 1EUR, even if I knew that it was knee deep in the dead. Who knows, maybe I'll fix'er up in the future, I have a knack for hard to solve cases.

Image Image

DO NOT BUY! was written all over it.

An idiot has learned some desoldering tehniques on a 3dfx card. What THE FU..........K?!?!? It's missing almost all of the resistors...a few solid capacitors...inductors...PCB pads...and God know what else...

Needless to say that the idiot still has a lot to learn...

Fortunately I have a Diamond V1 Rev. E in my collection and I was able to conduct a thorough examination...tens of missing componets...

Image Image Image Image Image Image Image Image

Scary? Sure, but these V1 cards are very simple and they can be repaired. What is desoldered can be soldered back. You need the missing parts, some soldering skills and an ounce of madness...I think that I fit the profile quite well..

After I knew the full extent of the damage I prepared the card for cleaning. No dirty stuff in my boxes!

Image Image Image Image Image Image Image Image Image Image Image

When I had my two V1 cards side by side I saw that my good V1 was missing an inductor so I made a transplant. Another missing part from the almost empty V1 is not a big deal. IMO.

Image Image Image Image

I searched on the internet information regarding the missing components and I found what I needed. Fate made it so that I also found at the flea market a HUGE card made in 1996 which is full of all the parts I need - ceramic capacitors, resistors and a bunch of other parts.

I think that you get my hint. It can be done if I'm willing to put in the hours or I can use this V1 as a donor card...all good alternatives.

Image Image Image Image Image

I paid under 3EUR for the card. Money well spent! A treasure trove of parts!

Protac Video Excel AG240D REV2.2 - Fastware Intel i740 Power 3D

GOLDEN BROWN!

MITSUMI CRMC-FX120T - CD-ROM 12x

Ahhh Mitsumi...CD-ROMs...I LOVE THEM TO BITS...call me strange I DONT CARE!!! :D

A soon as I laid my eyes on it I knew that it will come home with me. Still white and with few scratches it was begging for a rescue.

Image

It costed me under 3EUR. Cheap date I konw...

When I got back to my car I noticed that something was rattling inside and the tray would not stay closed when I pointed the unit with the face down... sheeshhhh only you could find this kind of stuff...no further commentary is necessary...superfluous stuff...

Let's restore this $hit!

A screw wasnt going to come out...drilling action required!

Image

Some superglue, transparent Poxipol, silicone grease, a little plastic surgery...good as new! MAN I'M GOOD!!!

Image Image Image Image Image Image Image Image Image Image

The unit was very clean inside and it doesnt have a rubber belt. All is based on sprockets...almost IMMORTAL stuff.

Even so, I cleaned it well... :D

Image Image Image Image

The good stuff.

Image Image Image Image Image

Clean bill of health.

Image Image Image Image

During testing I noticed that sometimes the tray would open right after I closed it.

I opened the unit and I tweaked a little the micro-switch that was responsible for this behaviour. Problem solved!

Intel Pentium II 350MHz - SL2U4

Opened, cleaned, custom thermal pads made from soft blue AC thermal pads, some AC MX-4 and that's all she wrote....

More words aren't required...

Don't be fooled by the short presentation, a lot of eblow grease was needed to obtain the results presented above, but I think that you already knew this...aaaa and before I forget I dont like working with half measures...but I think that you also already knew this...who knows maybe YOU, the readers know me better than I know myself :D. Next year in February 2019 I will celebrate 4 years since I started this incursion into the past...

Time flies...

More later.

Worakls ft. Linda Clifford - Porto (Nuno Cacho Lovers Mashup)

Intel 80486 OverDrive 100 MHz and friends

This story came out of nothing.

All started after I found at the flea market, my second Intel 80486 Overdrive 100MHz - DX4ODPR100 / SZ959 V1.1 CPU, which this time was complete and it came with the original heatsink. For this gem I had to pay arround 5 EUR and I had to use all of my haggling skills. The gypsy that sold it, told me to quit messing with him. This guy really didnt like my offer that was less than half of the asking price. I know him well and in the past I bought stuff from him, so I wasnt put off by this. You have to insist and also to present arguments, otherwise he won't sell a component even if he knows that he might not find someone else to buy it. He's quite stubborn but once you have passed his defences and start buying from him, prices drop considerably. The sight of money in your hand helps a lot.

The CPU was dirty, had a few bent pins, several fins from the heatsink were out of line but otherwise it was complete.

Image Image

After a little work it was almost good as new. The label has faded but it is still easy to descipher. I test fitted the CPU in my socket 3 Jetway J446A V2.0 motherboard and all went well.

Image

Some time after this moment, coupled with the fact that my repairing and restoring skills have increased, I remembered that I have in my possession two socket 3 motherboards which were put in the BOX of damaged components.

The two socket 3 motherboards are:

* Kaimei Electronic Corp KM-S4-1 Ver: 1.1 - bought from the flea market in April 2016.
* Jetway J446A-V2.0 - bought in February 2015 with my first batch of old components.

Both feature a SiS 496/497 chipset combination. They are solid and versatile motherboards. I really like this type of socket 3 motherboard as it makes me remember the ZIDA Tomato Board 4DPS that equiped my first PC in 1996.

I took out the two socket 3 motherboard from the BOX in which they sat and I conducted a thorough examination. After this examination, I came to the conclusion that both of them were prime candidates for a full recovery.

I was prepared to do everything that was possible to recover the motherboards. I felt confident and I was looking only at the final goal: the complete recovery of the motherboards.

Kaimei Electronic Corp KM-S4-1 Ver: 1.1

I tackled this motherboard first as I thought that it had fewer problems to solve. Little did I know...

A trace that was placed in the middle of the CPU socket, was torn and its ends were up in the air. I found out about this problem right after I bought the motherboard and I started to clean it.

Image Image Image

I used a multimeter to determine from where the trace came and where it went but this proved quite difficult and in the end I got nothing.

I evaluated my options and I wasnt going to desolder the entire CPU socket just to see where the trace went, so I decided to remove the cover of the CPU socket hoping that I might get a better view of the situation.

After I removed the CPU cover I found more problems. Even if the holes in the cover were pristine, beneath this cover, four pins in the CPU socket were damaged, three bent inward and one a little deformed. What the hell happened?!

Image Image

I didnt lose too much time searching for an explanation and I made from a soft needle, a tiny hook with which I was going to try and mend the damaged pins of the CPU socket. Initially I wanted to take four good pins from another motherboard, but I gave up on this idea as I suspected that they might have a shape that would not permit me to take them out of the socket even if I was to desolder them.

Even on my first try, a tiny metal piece broke off from one of the pins of the CPU socket that was bent inward ...in the end all of the pins that were bent inward lost the same tiny metal piece. The good news was that the oposite part of these pins was still in place and I bent this part a little, until it was at an angle that was needed for them to make contact with the pins of the CPU. The fourth pin of the CPU socket has survived the procedure.

Image Image

After I completed this task I made a test. All was OK! The force required to secure the CPU in the socket and all the noises made during this procedure were good. Dire Straits - Going Home

Image

The removal of the CPU cover has yielded ZERO clues in regard to the PCB trace...

After I inspected several good motherboards I came to the conclusion that perhaps, I have nothing to worry about, and the part of the trace that went under the CPU socket probably didnt touch anything, so I positioned it at angle that I deemed to be correct.

I used a thicker wire to bridge the ends of the torn trace.

Why I used a thicker wire? The trace is made from a very fine copper wire and even if I used my 15W soldering iron there was a good chance that I might burn it. The thicker wire would take a lot of the heat that was needed for soldering and the trace would have better chances of survival. I dont have a trace repair kit but I know how its done professionally. No big deal if you have what you need. As I didnt have the required tools and materials I used what I had at hand.

Image

I fixed the thicker wire with transparent POXIPOL not only to hold it in place but to also insulate it and avoid a contact with other components. The ends of the torn trace were cleaned of laquer with a sharp blade and MAXIMUM ATTENTION so that the solder would adhere as it should. Any mishappening at this moment would've meant THE END.

Flux, solder, 15W soldering iron.

Image Image

After all this work I conducted a final examination of the motherboard.

BEHOLD! A monkey has played with the solder joints of the MOSFET and has even scratched the PCB. Pfffttt.........I have to fix this mess too.

Image Image

After a good IPA 99% bath I was ready FOR THE BIG TEST!!!

Did it work? He he, of course IT DID!

Image Image Image Image

RETURNED FROM THE DEAD!!!

Image

Now came the moment to recover the second socket 3 motherboard.

This was going to be a tough nut to crack...

Jetway J446A-V2.0

Image Image

Problems that needed my attention:

1. 6 capacitors were missing 1uf 50V, 10uf 25V, 470uf 16V - TC1, TC2,TC3, TC4, TC20, C45
2. Missing MOSFET and missing information regarding the specs of the MOSFET.
3. The plastic cover of the CPU was damaged.
4. Many bent pins of the memory slots.
5. One memory slot was missing the tiny plastic hooks that keep the memory stick in place.
6. Hundreds of bent pins on the back of the motherboard.
7. The BIOS chip had a torn pin that had been soldered back.
8. ZERO JUMPERS PRESENT! about 30 pcs.
9. Bent pins in one of the ISA slots.

WHAT A MESS!! Even so, I was determined to do something about it and I wasnt going to quit.

I CAN SAVE THIS MOTHER OF ALL BOARDS!

The missing capacitors.

Image Image Image Image

The memory slots.

Image Image

After very tense minutes I managed to straighten all of the pins of the memory slots. Subsequent tests made with various sticks of RAM have revealed that all of the pins were making good contact with the pads. The sticks of RAM that were inserted in the top memory slot, the one that was missing the tiny plastic hooks, were held well in place so I had no reason to replace the slot.

Image Image

GET BENT! I had to straighten a lot of the pins on the back of the motherboard as many even made contact with another. A BIG NO NO when I was about to power up the motherboard. INDIAN SMOKE SIGNAL FOR SURE or 4th of July sparks, depending of the situation.

Image

A new cover for the CPU socket was taken from an incomplete motherboard.

Image

The damaged ISA slot. Again tense moments. The bent pins make good contact now but I won't use this slot unless it will be absolutely necessary.

Image Image Image

I soldered the missing caps. Instead of a 470uf 16V capacitor I soldered a 470uf 25V SAMXON (GT) Long life/High Ripple/Low IMPEDANCE. It's bigger but I was able the shoehorn it in. The tiny 1uf 50V and 10uf 25V caps are the brand that I found localy: Huang and ChongX. Mr HUANG & ChongX told me: ME FIX YOU UP GOOD! So I used them. :D

Image Image Image Image

I identified the specs of the missing MOSFET. My working J446A V2.0 motherboard has offered the information I needed, together with a not so great piece of news.

The heatsink required to cool the MOSFET had a special shape.

Image

I searched high and low for a heatsink but I couldnt find anything that would fit so I had to order more models. I also had to order the missing MOSFET and 100 jumpers.

REINFORCEMENTS HAVE ARRIVED! Daft Punk - Veridis Quo

Image Image

The heatsink must be placed under the MOSFET and the MOSFET has to be tightened well with a screw, a washer and a nut.

The ordered heatsinks were all too wide and they wouldn't fit well on the PCB. They were the smallest size that I could buy and I wasn't going to grind them down to size and lose some of the cooling capacity.

I wanted to put the MOSFET in a straight position but it didnt have support.

Casse-tete probleme!

In the end I used a heatsink that was more suitable. I used a second nut to distance the heatsink from the surrounding components, I arranged the legs of the MOSFET in the required position, I soldered nicely the MOSFET, I even found a red washer like the original one.

AS GOOD AS IT GETS! Excellent results! (Pads himself on the back for a job well done.)

Image Image Image

Pictures with the soldering job.

Image Image Image Image Image Image

More pictures with the MOSFET.

Image Image Image

Capacitors.

Image Image Image Image

After all this hard work I was ready for THE TEST!

I powered up the motherboard and I waited anxiously for the right noises and sounds.

NO POST! NO BEEP! NADA!

Sheeetttttt!

I looked closely at the motherboard and I saw that the graphic adapter didnt go all the way into the slot because one of the jumpers was in the way. A common problem back in the day.

Image

I moved the graphic card into another slot and I tried again.

BLACK SCREEN! NO POST! NO BEEP! NADA!

#$&@*$&(@*&$*(@#~~~~~!!!! :D

Hmmm...

Before I powered the board I removed the BIOS chip and I verified to see if the BIOS file was good. I didnt find the same version but I looked at another BIOS file and all seemed to be order. I used the HxD editor. At that moment I didnt write a newer version because I thought that maybe the version that was present on the chip was the right one for this motherboard.

Out of options I programmed the BIOS chip with the version that I found on the internet.

Image Image

I crossed my fingers and I pressed THE POWER BUTTON!

CLANK!

BEEP!

I'M ALIVE!!!

The satisfaction was off the scale. Oh the JOY! I breathed deep and I said to myself GOOD JOB!

First I inserted a single RAM stick then four and all of them were recognized, sign that all of the RAM slots are operational.

I tried an AMD 5x86 133MHZ ADZ CPU and the Intel 486 OverDrive 100MHz.

ALL SYSTEMS NOMINAL!!!

Image Image Image

Cleaned and repaired.

Image Image

A JOB WEEL DONE!

Image Image Image Image Image Image Image Image

I took pictures of my good J446A V2.0 together with the repaired motherboards.

Image Image Image Image

A nice spread dont you think? :D

Now my collection has two new socket 3 motherboards that are in good working condition.

It pays to stick to your guns and never give up once you have established a goal. :D

A few years ago I labeled these types of boards as organ donors but now I know that I can save them.

Merry Christmas!

Saber Rider Metal Theme - High Quality

The SUPER

Like many other situations in the past, the way that this board has found its way to me, it is af if, it had my name written all over it. She was searching for me but I was playing hard to get.

In July 2018 I was having a session of physiotherapy because I lifted something too heavy in the wrong way. While the doctor was doing her work and I was lying on the bed, having nothing better to do, I opened the WhatsApp application on my phone, to see if I had received a message. BAM! ONE MESSAGE: "What do you think about this DUAL CPU motherboard?".

-Hmm...NICE piece of KIT you have there. How much is the DAMAGE?
-$$$
-That's a fair price I said. Let me think about for a few days.

Looking back, I had no reason to wait and I should've snatched it right away, but me being me, I had to do my homework before I would buy it.

What was the DUAL CPU motherboard that I'm referring to?

SUPER/SUPERMICRO P6DLS REV 2.1 - Intel SLOT 1 440LX DUAL CPU

The manual stated that the motherboard supports Pentium II 233/266/300/333 MHz CPUs on a 66MHz bus. Now, the board had my full attention.

https://www.supermicro.com/manuals/motherboard/440LX/MNL-607.pdf

I searched for information regarding this model on the internet and I found a particularly interesting webpage written in russian. I used TRANSLATE and I obtained some valuable information.

http://www.phantom.sannata.ru/konkurs/2017/kt1701.shtml

From the translated text, one paragraph was very important as it stateted that if the VRM of the motherboard was equiped with a Cherry Semiconductor CS5155 chip, then it would support more CPUs than those stated in the manual. The CS 5155 can provide a voltage range from 1.3V to 3.5V versus the CS5150 which has a voltage range from 2.1V to 3.5V. The Vcore voltage is supplied automatically as this motherboard doesnt have OC features.

Why is this so important? Well, I can use Pentium II Deschutes(Vcore 2.0V) CPUs that run on a 66/100MHz bus besides the Pentium II Klamath (Vcore 2.8V) models specified in the manual. It is understood that the 100MHz bus Deschutes that will run on a 66MHz bus are going to function at a lower frequency than what they are cappable of. Let's take for example a PII 350MHz/100MHz Deschutes which has a 3.5 multiplier. If we multiply 3.5x100MHz=350MHz. On a 66MHz bus we will get a much lower frequency 3.5x66MHz~233MHz.

Besides all the aspects mentioned above, I also had an ulterior motive for wanting that CS5155 chip. I was planning to use two Celeron A SLOT 1 CPUs. I already had one Celeron 333MHz Mendocino core SL2WN (Vcore 2.0V) CPU which I bought from the flea market.

I asked the seller to send me a few pictures with the VRM area, to see if the CS5155 chip was present. From what I have read on the internet the CS5155 isn't usually seen on Revision 2.1 motherboards.

In a way I was looking for reasons not to buy this motherboard...

I received the pictures that I needed: CS5155 REPORTING FOR DUTY SiiiiiiiiiiiiiiRRRRRRRRRRRRR!!!!!!!!

YES!

After more WhatApp conversations I found out that the motherboard belonged to another contact of mine and the one that sent me the pictures was selling it for him. I knew both of them pretty well as we have made several transactions in the past. Over the phone I received all the information I needed from the owner of the motherboard and from the one that sent me the pictures and was selling it for him, I bought two Celeron 333MHz SL2WN SLOT 1 CPUs and I also received the confirmation that the motherboard was in good working condition.

Pretty complicated isn't it?

I had several opportunities to obtain DUAL CPU motherboards but I didnt buy any of them as they didnt speak to me. With the P6DLS it was different. As soon as I laid my eyes on it I knew that it was mine. The size, the emerald green color, the fact that it is a SUPERMICRO motherboard, a company that I still respect very much, the quality of construction, made me melt and I paid the asking price.

MINE!

I waited anxiously the arrival of the motherboard which had my name written all over it. When the courier came, I received a somewhat curious package.

Image

A TOILET SEAT? I mean the package from a toilet seat?!?! That's something! I sure hope the contents aren't shitty.

I removed the components from the box and I took a few pictures. This thing right here is THE REAL DEAL.

Image Image

CS5155

Image

440LX

Image

It was obvious that the motherboard hadn't been used for some time. Even so, it wasnt too dirty. Dust and grime according to age.

Image Image

While I was waiting for its arrival I kept asking myself if I will be able to use two Celeron 333MHz SL2WN CPU in SMP configuration. I already read how to execute a Celeron A SMP mod. A tricky procedure that it is within my ability to perform.

http://www.ptrlabs.com/celeron/index-sepp.html
http://www.hardware-one.com/reviews/dua ... cel2.shtml

Right after I received the motherboard I updated the BIOS with the latest version straight from the SUPERMICRO webpage. The description stated: "Supports Pentium II/Celeron Slot1". I mounted two Fractal fans on the two 333MHz Celerons SL2WN CPUs and I was ready to go.

https://www.supermicro.com/support/bios/archive.cfm

Image Image

As expected, the two Celeron 333MHz SL2WN CPUs didnt work in a DUAL/SMP configuration and I needed to mod them. A not so thrilling proposition as I dont like to perform extreme/ireversible modifications on old components.

Image Image Image Image

To rule out any doubt, I wanted to see if the motherboard works in a DUAL/SMP configuration with two Pentium II CPUs. Because I didnt have two 66MHz bus Pentium II CPUs I used two Deschutes 100MHz bus CPUs. These werent even identical. One was SL2U4 and the other SL37F. Even so, all was OK. The CPUs ran at 233MHz(3.5*66MHz) and both of them were recognized.

http://www.cpu-world.com/sspec/SL/SL2U4.html
http://www.cpu-world.com/CPUs/Pentium-II/Intel-Pentium%20II%20350%20-%2080523PY350512PE%20SECC2%20(BX80523U350512E).html

Image Image Image Image Image

BIOS

This type of AMIBIOS interface wasnt too popular back in the day, but I liked it. The motherboard has an onboard SCSI controller.

Image Image Image Image Image

After the Pentium II 350MHz test I decided to try my only Celeron 366MHz/Slotket combo that I had in my possession.

Image Image Image

I also tested a Pentium II 333MHz 66MHz bus SL2S5 CPU. In this instance I fiddled with the multiplier settings. From jumpers I was able to make it run at: 300MHz, 233MHz and 133MHz. When I ran the CPU at 133MHz the 512KB L2 CACHE was DISABLED and it wasnt detected at POST.

http://www.cpu-world.com/sspec/SL/SL2S5.html

Image Image Image Image Image Image

I even tried a Pentium II 450MHz SL2U7 CPU. This CPU ran at 300MHz and 200MHz.

http://www.cpu-world.com/sspec/SL/SL2U7.html

Image Image Image Image

Jumper settings.

Image

After all these tests I decided to buy another slotket and a bunch of Celeron - Mendocino core S370 CPUs. I gave up on the ideea of performing a Celeron A SLOT 1 SMP mod.

To be able to use Celeron A S370 in DUAL/SMP configuration, the slotket must have a connection between the B75 pin from the SLOT 1/SECC connector and the AN15 pin from the s370 socket of the CPU. If this connection isnt present you can solder a thin wire between them and PRESTO Celeron SMP ACTION! Some more advanced slotkets even have a jumper to ENABLE/DISABLE this feature.

http://www.hardware-one.com/reviews/dual370/dual370-3.shtml

Image

Pretty easy stuff.

THREE Celeron 333MHz CPUs SL2WN.

Image ImageImage

The P6DLS has the aura of a HIGH QUALITY PRODUCT. I dont even want to think how much it costed back in the day when I was still enjoying my AMD 5x86 133MHz PC.

Image Image Image Image Image Image

I laid the SUPER/SUPERMICRO P6DLS next to her 440LX sister, the EPOX EP-61LXA-M. There is nothing more to be said. THIS THING IS MASSIVE!

Image Image Image Image Image

A few bent pins, nothing too serious.

Image

The first task that I performed was the removal of a label that was placed in a bad spot. I maintained the label wet using a cotton disk soaked in IPA 99%, I added more alcohol using a syringe, I used a bamboo stick that wasnt too pointed and paciently I removed the label that broke in many many many small pieces. This was a stressful endavour The chances to damage something were pretty high and the label had a damn sticky glue.

Image Image Image Image Image

While I waited for the arrival of my second slotket and the Celeron S370 CPUs, I cleaned the two Celeron 333MHz SL2WN CPUs. It made no sense to clean the motherboard and then leave it on the desk for two days during testing.

Image Image Image Image

I washed the heatsinks with water and dish soap. The retaining clips took a bath in a mild rust removal solution and they were hand polished until they shined. I wasnt able to remove the pitting on one of them but in the end I got a more presentable result.

Image Image Image Image Image

SHINY!

Image Image Image Image Image

The white fans are nothing special. Maybe a little weak but still up to the task.

Image

ALL DONE!!!

Image Image Image Image Image Image

CLEAN!

Image Image

The Celerons have arrived!

Image

After I received my second slotket, model 370SP Rev 1.0, I used it together with my Gigabyte GA-6R7 REV 1.7 slotket, to test all the Celeron A S370 CPUs. To my joy, a multimeter test, has revealed that both of them had continuity between the B75 pin and the AN15 pin. No modding required.

The SUPER/SUPERMICRO P6DLS motherboard worked well with two different types of slotket, in DUAL/SMP configuration, at 400MHz, 433MHz and 500MHz. AWESOME STUFF! I LIKE IT!!!

Image Image Image Image Image Image

After this much fun I had to clean again the CPUs that I used. What a mess.

Image

The moment when I had to clean the motherboard arrived.

BEFORE and AFTER!

NOT SHINY!

Image

I protected all of the stamped ink markings and the MADE IN U.S.A. logo with ORAFOL STONE GUARD film. I didnt want them to be removed by IPA 99%.

Ready for ACTION!

Sadly, I didnt protect the label from beneath the northbridge chip and it was removed by IPA 99%, ...it happens even to the best of us. I thought that the protection wouldn't be needed but as soon as it was touched by IPA99% and a soft brush, all the writing has disintegrated.

I dried the motherboard using a small air compressor. Two wash cycles and three pass of fine detailing were needed to obtain the results that I wanted.

Final results? MIRROR-LIKE! :D

While I was cleaning the board I had a lot of time to inspect it thoroughly. Minimal damage.

More good stuff.

This was the story of my first DUAL (Symmetric multiprocessing (SMP)) procesor motherboard. I dont know if I'll buy this type of motherboard in the future. Maybe YES maybe NOT.

Appart of bragging rights I dont see how am I going to use it. The 440LX chipset makes it to stand out. Even if I like the 440BX a lot, I'm also a 440LX fan, the first AGP+SD-RAM chipset for Pentium II CPUs.

Windows 98 knows nothing about SMP and I would have to use a version of Windows NT or Windows 2000. These last ones might have some quirks with some games and other applications.

If I'll include this motherboard in a Windows 98 SE build, one thing is certain. I will use TWO Celeron 500MHz CPUs. SMP support of not, I want all the SLOTS FILLED! :D

After many years of service, after more years of being kept in a case stashed in a dark corner, this motherboard, meticulously restored, is waiting paciently in a box together with her sistes, away from the teeth of the crusher, ready to tell the story of times gone by.
