By oiling the fan I hope you mean repacking the barrings. Oiling the daft will only last so long

And I hope you did not use wd-40 because that's not a lubricating oil.

Sewing-machine/gun-oil does the trick. When oiling, I usually peel back the sticker and leave it open with one drop of oil for 15 minutes. Then rotating a couple of times and put the sticker back. Remember to clean up if oil is spilled were the sticker goes. And I allways have the hole facing up. Gravity usually drags the oil down into the barring.

Don't eat stuff off a 15 year old never cleaned cpu cooler.
Those cakes make you sick....

I've replaced the CPU fan on my HP e-Vectra - the original fan sounded like a toy car motor and it didn't seem cool enough to properly maintain the CPU's temperature, the replacement fan (which is a Cooler Master 80mm fan from a busted heatsink) sounds much nicer and feels cooler so that's nice, I think eventually I'll get around to replacing the fans on the Antec PSU inside my Athlon 64 rig, I believe I have some donors that are just the right sizes which should make that process easier.

I'm retiring the Dell Dimension 4300S - that system was a bit of a pain to keep running especially with the replacement USB front hub causing Windows to start up slower due to the replacement front hub coming from a GX280 which has USB 2.0 unlike the 4300S (which is based upon the GX240) which has USB 1.1 so the much newer GX280 front hub board had the tendency to act up, the AGP slot being low-profile only is a major issue for its' role as a 9x gaming PC because it's hard for me to find "good" affordable low-profile AGP cards aside from crappy low-end Geforces, and taking a CRT monitor off of it just to take it apart gets old quick, I've ordered an Optiplex GX150 Mini-Tower to replace it so hopefully that works better.

I thought focus was usually fixable via 2 internal knobs (which on one occasion I've made externally accessible by cutting a hole in the casing). Why throw it away over such an easy fix? Even if you have to adjust it every couple of days it's only 2-5 minutes of work.

It'd be one thing if it held a specific focus consistently, but I'm talking about it staying in focus for a few hours, then suddenly turning into a blurfest when it's stayed on too long. That implies far more extensive work to properly fix, on top of the fact that the internal speakers were not working at all. It'd have to be a full-on refurb project.

You also have to take into account how often I get complaints from my stepfather for having too much old computer hardware in the house that he just wants to get rid of, even before I took in that last batch of stuff. As it stands, I have a few other CRT monitors to use that outclass the old Multiple Scan 15AV quite handily, even if they lack the period-appropriateness of an actual Apple monitor. If I gotta downsize, the non-working stuff goes first.

Also, If I'm going to tear open a CRT for repair, my dead GDM-FW900 comes first (I think the D board/flyback gave up the ghost, but left everything else intact), followed by my dying GDM-5410. It's hard to do better than those, even if Sony seriously dropped the ball on FD Trinitron production somewhere for them to all be dying out like this. The FW900 is especially worthy of resurrection, but spare parts are expensive and hard to come by, with a new D board being offered by someone on [H]ardForum for a whopping $300.

Even if the GDM-5410 outright died, I could downgrade a bit to this ViewSonic A70 I have in storage and still not have to suffer asstastic LCD quality on my retro systems. It's not the greatest of CRT monitors by any stretch, being a little 17" shadow mask that only does 1280x1024 at flicker-inducing refresh rates, but it's been plenty reliable in the time that I've used it. I also ordered a DB-15 to DE-15 VGA adapter, so it's trivial to connect VGA monitors like that to the 6500 or IIcx. (But I'll probably stick with the AppleColor 13" RGB monitor on the IIcx anyway; it works, it's period-appropriate, and it's a Trinitron.)

Added a 5.5V 0.22F super capacitor to my 386 motherboard. Works like a charm !

supercondo.png

All I need now is to glue it in place as only one of it's leg is really soldered in, as you can see, that cap was too short so I had to add a wire

So how do you plan to recharge it some day when it drains? Or replace it when it drains? It looks like a permanent install... 😕 😕

The deadly varta batteries are accumulators so the motherboard recharged the battery. Now that a supercap is in there, it gets recharged every time I turn the computer on just like the old battery ^^ that's why when you replace varta batteries with CR2032, you need a diode to stop the recharge current and that's why varta batteries were soldered in place ^^

Got through the rest of my computer collection and wrote up spec sheets for them for reference. (e.g. CPU, RAM, HDD, OS, etc etc)

Liqmat was so generous to send me the IBM model 80 knockoff case in this post: I recently found this hardware, AKA the Dumpster find thread.

I got it in yesterday, and made a video opening it: https://www.youtube.com/watch?v=Tv49zs4lO4Y

Sorry for the poor audio, its been 90F+ lately (30C+) and I dont have A/C, so I was fighting fan noise.

It is a mistake to think you can solve any major problems just with potatoes.

Tried to update my Abit TH7II bios with a Willamette 1.6 GHz P4. No dice. Still says something about a lockout jumper.

Anyone have any ideas? I'm using Award899 and the bios from:
http://soggi.eu/motherboards/abit.htm#S478

Trying to find another version, not having much luck so far.

Edit: Found some random website with what seems like legitimate backups of the Abit TH7II bios as well as the awdflash program. Tried the (latest - 1) BIOS. No flash success... it was just stuck on flashing. At least my system can still boot to floppy. It just makes a very annoying wee-woo wee-woo sounds.

Great video and I am very glad it got a good home. It was on its way to the recycle center so a nice save for sure!

Well, this is rage-inducing. It seems like my Power Mac 6500's floppy drive suddenly doesn't want to work despite having worked just fine before, because it suddenly can't read ANY of my disks, even the ones it read just fine before.

I suspect it may be a poor connection along the motherboard edge connector somewhere and that I'll have to reseat it. The drive noticeably clicks and whirrs, it just can't read anything, and a formatting attempt on one of my more expendable disks didn't actually rewrite the contents at all despite its best efforts.

If this doesn't work out, I'll have to try and read the disks (at least the 1.44MB FDHD ones) through my P4EE box, presumably through Windows XP, and all while keeping the data intact. I can't use the IIcx for this while it fails to power on, so I'll just have to order the caps on my next paycheck or two.

Damn shame, since the 6500 is a good bridge machine because of that very floppy drive, while still being modern enough to use USB and Ethernet through PCI cards. I need to figure out how to make it work again.

On a brighter note, I got around to opening up this box of IIcx-related books that I overlooked at first. A lot of them cover ancient productivity software nobody deals with in a post-MS Office world, but one of the unexpected inclusions was a Falcon MC manual and disk. This oughtta go nicely alongside my Falcon 4.0 binder.

Had to reinstall Windows 98 SE on 1 of my Pentium III PCs, as it was missing system files for some reason.

Once I'd done that, I decided to install BeOS 5 Personal Edition to have a play around with. I used to run BeOS 5 back in the day on this same PC and the spec hasn't really changed that much since then.

Spec:

Gigabyte GA-6BXE Rev. 2, Slot 1 Motherboard
Intel Pentium III 650MHz
512MB PC100 SDRAM
40GB IDE HDD
Nvidia TNT2 32MB AGP Graphics
Sound Blaster Live! 5.1 PCI Sound
Intel Pro 100/S PCI Ethernet
Also dual booting with Windows XP Pro.

After installing the Nvidia driver for BeOS/Haiku, it seems to be running quite nicely. The GL Teapot test before the Nvidia driver was installed struggled to get 30fps with the default small window size, after the driver install it was hitting over 130+. 😎

Only played the BeOS port of Duke Nukem 3D: Atomic Edition so far and that ran well also. I'll have to try and dig out the BeOS port of Quake II to experiment some more.

I tried to run the port of Wolfenstein 3D, but was unsuccesful so far. I did manage to install the trial version of Opera 3, which allowed me to access the BeBytes website and download some software. I'll need to play around a bit and try and figure out how to install Firefox 3 or SeaMonkey 1.8.

I also installed the Haiku OS on this PC and played around with that for a bit. Other than offering access to a more up to date web browser and some other modern improvements, it wasn't all that useful for me due to the lack of compatibility with many BeOS apps, so I'll probably just install BeOS 5 Professional or the "Developer Edition" at a later date instead.

Decided to solder on 2 new jacks for my Aztech Sound Galaxy NX Pro since the left channel was getting weak/erratic at times. The jacks that were the culprits were the line in and microphone jacks and fortunately, I have a lot of jacks left and they did fit nicely on the card and it was successful, even though my soldering skills aren't great, and my MacGyver mode was set to full throttle to remove the busted jacks.

The next project for that card is a new potentiometer, which is hard to find that online these days, unless I can find a sound card parts website and purchase a new One, a desoldering iron with the pump, and desoldering braid as well (solder wick).

Looking at one of my cards here and you could pretty easily retrofit a regular modern 5-post wheel volume control onto the card. You would just have to run a couple wires for posts that don't line up with the holes on the card.

Really cheap on eBay. Just search for:
volume potentiometer wheel
and match up the value you need. Measured my card and it looks like it used close to 10k for the max resistance. Make sure to get the 5 post + ground... I think they should work, you just have to work out what legs to use.

Here is an instructable that may help.

I removed the potentiometer on my Sound card since it was erratic at times and rusty. Here's the pinout of the sound card for the potentiometer:

Decided to take a potentiometer out of a busted portable cassette player (was the volume potentiometer) to make a balance control for an Aztech AZT2316R that has balance issues in the outputs, and I have to say it's successful.
