I've got the FIC VA-503A board, it shows the pinout in the manual, it is just a regular USB port backplate cable: 2021-03-06 21_28_11-va503a_2.pdf.png For the CPU support have a read of the unofficial K6 III support page: http://web.inter.nl.net/hcc/J.Steunebrink/k6plus.htm Sadly, the link for the …

You need to look for the Dell PA-1 charger, you can also search for "dell 18.5v" and get some results that way. It's got quite a distinctive plug with that rounded end. Here's what one looks like from a search: dell-pa1-1.jpg dell-pa1-2.jpg dell-pa1-3.jpg I should really buy one of these some day, …

That's great that you managed to get them back without breaking a single pin off :) You got me worried that I had lost my K6-III+ processor, it wasn't on the board it came with where I thought it was. I found it on another MVP3 board I had. It turns out I have so many Super 7 boards now that I'm …

I have an unfortunate but interesting update to this, regarding the FM audio on the card. This has been installed on my little test PC and I found that sometimes when plugging in speakers, the whole computer would power off. Last night I was testing it out since I haven't in a while and found that …

I love the look of this project as a complete solution :) If I can improve this design, what should I add, include or change? There are some things I'd love to see from one of these projects: 1. An on/off button solution to handle the momentary switch of ATX cases to operate as a latching button, …

which one? I designed one for the CT1320 that prints nicely on an FDM printer: https://www.thingiverse.com/thing:4577516/files Not the smaller type used on the SB-pro 2, SB 2.0 and early SB16 cards though. I have an SB-pro 2, so I could potentially check out its dimensions and design up a 3d …

I just had a really not-fun but truly retro activity last night and this evening. I decided to swap over my Voodoo 5 Tualatin PC from my Abit VH6T in an ATX case, to the Micro ATX Chaintech 6VIA5T in an In-Win D500 MATX case. Which was funny since the Voodoo 5 actually hits the floppy drive in its …

My experience is very similar to dionb's; A lot of the Fortron Source (FSP) or Aopen power supplies can be sold quite cheaply used, they're reliable (imo) and given that many are from the era of the Athlon, they've often got 30A on the 5v rail. PC Power and Cooling and Seasonic are also good to look …

Watch out for the CMOS batteries in those mid 90s laptops, I found even the Toshiba Tecra 8000 can be ruined by a bad CMOS battery, which sits somewhere under the palm-rest. You have to dismantle the whole thing to get at it. Personally I just remove them and treat the area. So many of my Toshibas …

I'm still interested whenever you feel ready to go ahead with a larger run. I agree with your point about soldering the QFP160, that's a bit too hard for most people. I'm moderately good at soldering, but I hate soldering large QFP chips. If you've got a stencil or you're good at drag soldering, …

Regarding the floppy drive issues, have you tried swapping out the RAM? I've had similar problems with late 486 boards not allowing the floppy drive to work with EDO ram installed. But it works with FPM.

From what I can see on the snark barker's schematic that TubeTime put together, you could do that potentially by wiring the left channel to either positive or negative of Capacitor C1, then the right channel should be either leg of C14. Those both come straight out of the volume wheel and feed into …

Thanks for the warning, if that happened to you, perhaps I should rig up a proper power switch for it after all. The PSU I'm using on that PC isn't exactly high quality, so I'll definitely consider it.

Nice selection of tracks :) That little setup is incredible - especially knowing it's all coming from an 8086/80186 class processor, the mouse really tops it off I think. Have you tried out PS/2 to serial mouse adapters with their own power source to see if that helps? Then you're not tied to that …

Try searching for "31 card edge connector". It looks like there's some "50-31SN-12" in the states and they look correct for 8-bit ISA.
