I've had success with EZ-Drive on a very similar setup. I used WhatIDE to get card geometry. But I've always been curious to go the XT-IDE route. For someone without a programmer, it seems like a preconfigured ROM from Monotech is a cheap & easy route. Or one of their DoubleROM ISA cards. Any …

So what about tapping …

I assume your video card and the drivers you're running are going to be an important part of the troubleshooting here.

I got the system re-assembled on the bench, so I could have a look at the bespoke software it's running. Useless to me, but neat to see. And the startup sequence gave me some additional confirmation of the purpose of all the cards. This is CGA composite out to an old TV, snapped with a phone, so …

Was the colored ribbon cable and box also part of the setup? I would have taken the case and crt but not the keyboard... It was. Part of me wanted to keep it all together, but it would have just filled up more of my storage space forever. The monitor is composite black & white only, and would be …

Not knowing quite how long this had been in service, I was assuming it would contain an early Pentium AT board …

I added a wavetable header to it and it works. You need to bridge R29 and R34 on the card in the first post. The wavetable audio will be on the AUX2 input of the cards mixer which is muted by default. Nice work! Plug a Serdaco E-Wave into that and you've got yourself a DIY Compaq Business Wavetable …

I'm sure this is a really dumb question, but I'm not afraid to look dumb. Let's roll. So there is this sound card: https://www.vogons.org/viewtopic.php?f=62&t=79145 It has the cheapest sounding wavetable in the world. See for yourself . But what it also has is a 512k socketed ROM chip. The AdMOS …
