Got these three CPUs today: 486SX-25, 486DX-33 and P133.

Bought a CM-32L & CM-32P today to add to my Roland modules stack. 😊 They should arrive late this week / early next week.

i read tonight the cm32p is just like my roland u110 except that the output is actually cleaner..
this actually a really shitty thing about the u110 it sounds noisey on the output

have u ever hooked this upt o a midi controller + played it?
can u confirm the cm32p has no audible noise?

Here are the pictures. I also put the jumper on P which means I/O 330. That was the same with the other 1 I bought. That 1 works. Without the P jumped it does not work.

It may or may not be the scratches. Maybe the ROM is blown as well. Who knows.

is this the dead card that started teh clone process?? 😁

There a hard to find any information about this upgrade. If someone know detail about changes - please write to me.

did u do this upgrade? or did u just find it like this?!?!!?

Epox EP-8RDA3+ Interesting NF2u board, Barton 2500+ is under the heatsink. I'm curious how it will perform in overclocking compared to Abit NF7. 😀

Abit SD7-533 One of the P4 boards supporting AGP 2x 3.3V.

Heh, been a few years since I've seen one of these. I used to own and used it quite a bit with a mobile Barton (unlocked multiplier for the win!). Feature wise, it was a pretty fantastic board for 2002-2003. However, in my case, there was some instability and issues that crept up from time to time. Perhaps it was the result of faulty capacitors, however it was a bit temperamental overall.
Hopefully, yours will be a fine experience!

According to Cloudschatze, all of PA Spectrum 16 and Studio 16 cards require -5V, except for 650-0097-xx (IXW-SCSI 1-1) Pro Audio Studio XL card. I am not sure if he has every PAS16 variant, but indeed he owns a 650-0060-xx (IXW-PAR). It seems IXW-PAR needs -5V.

this means this card requires a specific PSU to work properly???

Any standard older power supply for early ATX and AT will provide -5v, but it was removed from "later" power supplies. I don't remember when the exact switch over was. But yes, you will need an older one for the system. If it's a card that requires -5v then new power supplies you can buy today will not provide it.

It was removed in the ATX12V 1.3 standard, apparently.

Just get yourself a new power supply and use one of the ATX->AT adapters with -5V on it.

Also, all AT PSUs should have provides -5V, and all early ATX PSUs have those as well.

I happen to have an AT PSU without the -5 line, so keep an eye out for that. 😉

Definetely hooked on old pc hardware now! Bought an external usb Zip 100 drive from a charity shop for 50p and then bought two more (internal Zip250) from ebay. One of which was brand new never used and the other is used but comes with the beige 5.25" adaptor plate

These are going into my 486 build and my Pentium 233 to aid with file transfers. I also got my 486 an ISA network card which as well as network also does XTIDE duties.

Also scored this for £15 from Ebay, more than i wanted to pay but worth it!

-5v was only used for the ISA bus. When ISA went away so did -5v.
No ISA slot doesn't necessarily mean there is no ISA bus on the board though. Sometimes they used it to support onboard chips.

Just keep in mind that ZIP250 drives work well only with 250MB disks, they can read and write 100MB disks, but that's really slow. It takes an hour to fill a 100MB disk on my ZIP250 USB. ZIP100 ATAPI on the other hand is doing the job much faster.

I can't remember mine being that slow with 100MB disks, or at least not significantly slower than the 250MB disks...or at least not dreadfully slow 😊
Btw, I think my 250MB USB ZIP drives are some of the nicest and most modern looking old gear I have! 😁

These are still in production, but they have a copyright date of some 13 (almost 14) years ago;

If you know what that is, recent events might be making more sense than they were before. I got this one with adapter cables for ~£25, I think that's reasonable. Technically free because I got Christmas money, but that is in cash, so I will spend that on groceries - technically I spent it on the card, but eBay doesn't accept cash, so I just swapped them around.

Let's spice things up a little!

I got a hoard of stuff for free this December. Prepare to hate me 🤣

1. A dual Socket 5 server:
- 2x Pentium-100
- Intel AltServer motherboard (codename "Altair") complete with cache module
- 32MB FPM RAM (Registered?)
- 3 SCSI Hard drives
- a SCSI CD-ROM
- Intel Columbus chassis (Classic!)

Sorry, haven't had time to clean it yet.

2. SCSI caddy loading CD-ROM. Two sreamers, Colorado 250 and Tandberg Data something with a lot of casettes. (sorry as well)

3. Gravis Ultrasound MAX 2.1 - confirmed working

4. Acer/AOpen VI14G VLB motherboard with nice big cache chips

5. Some RAM, 2x4Mb SIMM 30-pin, nothing interesting apart from that.

6. A nice PCMCIA LAN card, a CF2PCMCIA adapter, an IDE40/IDE44/SATA 2 USB adapter - all pretty handy!

7. A mighty bunch of cables and stuff including a "888" frequency indicator, a Voodoo passthrough cable and a pair of new 5.25" to 3.5" rails.

8. Two PCI rizers and yet another Amd X5

9.SB AWE32 CT3910

10. SB32 CT3670 - the third one in my collection

11. Miss Melody (ESS 688). Should work well in XT.

12. 3dfx Voodoo Graphics - Diamond Monster 3D

13. ATI Rage II+ DVD. Good thing that it's PCI, I don't need another AGP Rage...

14. Cirrus Logic GD5428 VLB with memory expansion installed. That's probably 2MB, am I right?

15. InnoVision Savage 4 Extreme. I guess not extreme enough to make a good card...

16. Slotket 370SP with Celeron-400. Mendocino only 🙁

17. A VLB controller card. I've been looking for one of these.

18. A couple of suspicious Adaptec SCSI controllers.

19. Abit Hot Rod 100 PCI IDE controller. Should be a great addition to old PCI gear, I think of using it in a Socket 4 system some day. btw, the name is so stupid, it's kind of cool.

20. 3com Etherlink XL PCI LAN card. I've been looking for one of those!

21. SMC FDD+I/O controller card. Should work in XT.

And last but not least, Microsoft InPort mose with InPort controller (1986)! This will fit nicely into my future XT!

Hi there. I believe your problem is that you're using 1MB chips instead of the 256KB chips that are installed on the board.

Loving it! 😁

Your s5 system, the modules you mention "32MB FPM RAM (Registered?)", if you want, could you post a pic of the modules?
I remember once having stripped a dual s5 or s7 system on the street and the modules you mention sound to be similar (the case was way too heavy, but I did take the chips and the memory modules and they were also FPM I think).

Your VI14G looks similar to the VI15G I have and it seems yours also has gold-plated SIMM slots.
The cache chips you seem to have on your board seem to be the ones you need 8 of to have 512KB cache, so I reckon yours has 256KB cache in total?
I think mine came with the smaller ones.
I read in the past it was a bad idea to mix metal types because of corrosion, but in later years I've also read that this wasn't as much of a problem as it was made out to be. Since I have plenty gold-plated FPM SIMMs that doesn't really bother me though and you seem to have gotten a couple gold-plated SIMMs yourself, though I can't read the print to see if those are EDO or FPM. They have either 4MB (if the other side is empty) or 8MB (if both sides also have chips).

Your SIMMs with only 2 large chips are usually 4MB (the one with the very thick chips, if the other side is empty) and the other one with the very thin large chips should be 16MB if the other side is empty, but I admit that my memory is a bit rusty here 😊

And you got a GUS! 😁

And what's so special about the 3com Etherlink XL PCI LAN card if I may ask? 😀

Great haul! 😉

Do you mean the datecode that's usually printed on the PCB?

Quad-monitor Socket 370 system with those 9" screens, I presume. Now what will you do with it is still a mistery to me.
