Wrangled with some ISA soundcards today. To be more specific, Yamaha SW20-PC, Reveal SoundFX SC400 Pro 16, Samsung Audio Magic X and an OEM HP Aztech 2320.
And somehow I revived 2 graphic cards, a no name S3 Trio 3D/2X AGP and a Matrox G200 PCI.
Nice, what did you do to get the video cards working again? I've had non-working cards work from just cleaning the PCI contacts or re-seating the BIOS.
I've been doing the same thing today on my slot 1 test bench setup - testing out the Yamaha DB50XG that I got inside of a computer I bought recently. I thought it had some fault because the main chip gets relatively hot going up to 60c?

It sounded very wrong playing passport.mid and canyon.mid but sounded fine in games. It seems to just be some mapping issue with those midi files since XG midis from FF7 play fine and games sound excellent with it.
Just to be safe, the Yamaha chip by the ROMs now has a flat ceramic 40mm heatsink on it since I've got a bunch of them for free and they do work.
*sigh* the card it fits best is the CT2950 soundblaster 16 but I heard the hanging note bug within just a few minutes of gameplay - time to modify the soundblaster's DSP with one from the Soundblaster DSP thread.
Then thought I'd finally test out my Tualatin mod on my MS6905 slotket - last time I used this slotket I thought I had completely broken it since neither tualatin or P3 worked so I read up and re-did it. Sadly I did that ~4 months ago and have no idea which mods I did. I plugged it into the board to test it and it works! 1.2GHz Tualatin celeron working on my Aopen AX6BC board.

Oh it was toasty though for some reason after about 2 minutes of operation and it's got a junk bin HSF on it right now just for basic testing.
Why is it so toasty??? The CPU voltage on the slotket is set to auto, that should mean it will go at 1.5v like the CPU says right???

Uh... checked with multimeter and it's running at 2.08 volts...
This 1.2GHz Celeron may not work for very long now - the slotket has manual voltage settings and it's now running at about 1.53 volts being set for 1.5v operation. Oops!
