swapped out P166 for P233 mmx 😳

cleaning corroded traces with a small nylon brush, need to bridge 7-8 broken traces now.

and getting some headaches as only the 2nd VLB slot works on the ISA486SV2 Rev 3.1

nice. noticed any difference in applications or games? i know benchmarks will show it, just wonder if its noticeable

And the results were B+ grade, overall. That Gateway 2000 case came out mostly white, marbing in annoying places, but I am on the hunt to use period parts to make it a DX 33 again 😁

I love all those cases!

The one on the far right is going to receive a Leopard Blue Lightning SLC setup. Gotta source a VLB I/O card and a VLB video card. I even have an IBM branded hard disk. 256 Mb. That's gonna be a fun build!!

What caused the corrosion under there?

Battery? If so, strange place for it.

Nice, reminds me of my Ikea Ryzen 5 (obviously not vintage) setup. I have a similar problem with my DVDROM, I have to open the door to get to it. It's locked up, as if I do leave it open, my kid will probably touch it and break it by putting his matchbox cars all over the motherboard. Boom!

no glue, no battery was installed on this FX-3000 (with ECS "local" bus). May it was out in the rain or on a wet place for some months

I'd say yes. Win98 ui and other functions seem a bit snappier. However its particularly smoother in games where the 166 would chug... in outdoor areas for example. Choppiness in compressed video playback is reduced to almost zero.

With a voodoo1, Quake 2 timedemo went from like 27 to 34 FPS at 640x480. DOS quake at 320x200 gives about 50 FPS iirc.

I was very pleased that this packard bell accepted and recognized the CPU as it seems these boards are hit and miss with support. My only concern is lack of a VRM, so I slapped on a decent hunk of aluminum + fan + a slight amount of artic silver. Gamed for hours, no lockups, I think I'm good.

Looks like a cat pissed on it. To get to traces only under the SIMM sockets takes some aiming ;p

interesting, thanks - it seems a pivot point for some games - that change in Mhz making all the difference, it is quite a proportional change. I have a P166mmx PC which seems good for anything of its time, but maybe i don't push it much, having only a 2d pci card

Helped a friend of mine finding a computer in his distant memory: An IBM with the shape similar to a Macintosh (classic) and codenamed "hummingbird" in traditional Chinese (蜂鳥).

Me: "Was it PS/1?"
Him: "Shaped more like PS/2 Model 25, but I couldn't find any additional info online."

I remember that IBM "hummingbird" ad, using it as an analogy of "small but fast and powerful."
Having a Chinese name hinted that it was marketed to East Asian users and must be capable of processing East Asian languages.
Must be a small form factor AIO of some kind (I remembered that Japanese customers loved classic Mac's SFF design; IBM and other companies might have followed the trend).

And bingo! Turned out it was an IBM PS/55Z 5530Z SX. 😄

or was that small, but buzzy and loud?

Repaired a GameBoy Color that didn't turn on, no display, and a bit of corrosion on the cartridge slot that caused my game saves to get destroyed and some game to not start up.

Used 30AWG wiring, solder, flux, and exposed trace copper to fix the switch issue, reflowed the IC between the volume wheel and the CPU to fix the display issue, and removed the corrosion from the 1 pin on the cartridge slot using IPA, DeoxIt F5 (couldn't find my D5), and a small screwdriver (flat tip).

Also, I fixed my Pokemon Red game by swapping the Blue ROM out and installing the Red ROM onto the cartridge board and it works without issues (also restored my save thanks to the backups I have).

What product did you use?

although expensive it would be awesome if someone made replacement x86 motherboards to reball components from damaged units given the age of x86 architecture i'm sure it wouldn't be a cpyright thing but a preservation effort

with some maintenance gameboy original and color seem destined to last many decades, i've heard of them found working after being abandoned or being readily returned to life several times. seems to be a robust handheld!

A bit of old fashion trolling on /r/linux. The result was far better than I expected...😉 Poor wee things.

What did you do, put the old "monkey linux" ( https://archiveos.org/monkey/ ) on a 4MB 386 then ask them how to install KDE?

Well, I sold my old apple IIgs system today. Kinda sad about that, but I really had lost interest in it.

Today, I tried to get a celeron mendocino working on a slotket in an old HP pavilion with an LX-based motherboard, to no luck: the screen doesn't even come on with a 300A. There also don't seem to be any BIOS updates available. Bummer.
