Re: Case Slot Fans and the Voodoo 3

Glad it's useful to someone :) I'm working on one for the PCI card now I recommend using PETG or ABS if possible, though it's purposely designed to be away from the card & heatsink, PLA can get a bit floppy if it's over maybe 50c - the other day I made a monitor stand part out of some dark grey PLA …

I was trying to solve this problem last week too - I made some fan adapters to fit a 92mm or 80mm fan to the card. It's about the same as zip tieing a fan to it, but attaches securely to the board holes with some 10mm (2000) or 15mm (3000) "m3 hex spacers". I've attached the STL files if anyone …

I broke one of my gotek drives by either doing something very wrong with wiring or I plugged the cable in upside down? Thanks to flashfloppy's special test firmware , I was able to find out which pins weren't working, the ouputs on 26,28 & 30. Sure enough, looking close up and following the traces, …

I tried that but it didn't work well with CD-roms either, which suggests maybe it's some other issue 😀 XT-IDE is a great option as well, I just like the LBA-Enhancer because of its simplicity in comparison. Overall, there's no real reason to choose one over the other.
Re: Newly made Gravis Ultrasound compatible cards ... what's the degree of interest?

That's the current plan ... I might have underestimated the effort of soldering ~200 InterWaves for the final run, which is prolly why I've been quite lethargic the closer the project got to being finalized. I've recently announced that change of plans on here. I've recently done some QFP soldering …

An SX 25, which would likely have a BIOS from 1991 / 1992 would not be able to handle any drive over 504MB without either a drive overlay or an LBA extension ROM (typically mounted on a network card) If you get a network card and install a suitable size ROM on there with this ROM installed: http:// …

Someone keeps selling old PC parts in the UK and he's finally started selling some of his broken stuff. I put in an offer for this nice Soyo 025R2 motherboard - I've now got too many VLB 486 boards, but this one is from 95/96 and has a voltage regulator. It's also got the ideal port layout for the …
Re: General instability with p3 1000 and msi bx master
Posted on 2020-04-10, 20:15
It shows Pentium III MMX on the bios screen - surely that should say SSE. What does it show for the CPU with the 800MHz P3 in there - could it be a microcode / CPU stepping problem? Or maybe it's a voltage problem, the detected CPU voltage is lower than the rated 1.7v.

The 256MB CF card that I was using for a hard drive on my favourite 386 broke recently. It was an old consumer grade card that got messed up after one too many power cycles at the wrong time. I've been keeping an eye out for good replacement 256MB cards and found a big lot of Cisco 256MB CF cards - …

It sounds like some of the voices aren't being played, or they're being cut off? I'm not familiar with the SCC-1 beyond being aware that it's an SC-55 + MPU401 on the same card. It looks like it's got 4 ROM modules, maybe one of those has some trouble, or there's a damaged trace / bad solder joint …

I think if your card got flexed when moving it from one PC to another or when changing a heatsink, that could be causing what you're seeing. I've got something similar, I had a working Voodoo 3 3000 that become not-working when I fitted a bigger heatsink to it. I heard a small *tink* sound when …

Sadly one of the cells was down at 1.5 out of its 3.7 volts, so it's a dud. It …
