I wonder if we could get a dummy IC package... :) If a dummy is all you need, you could take any random 28-pin chip, drill the die out from below and plug it in. ... Or look for the worst-rated Aliexpress shop for SID chips and buy a piece of plastic with legs from them. I would be afraid to plug …

I once had the idea to design an ISA POST analysis card, but later decided to use my time on other things for now :) I do have a bunch of notes though. These two sites have similar projects: http://www.malinov.com/Home/sergeys-projects/isa-post-card http://bbright.tripod.com/information/postcard.htm …

If you post the high-resolution pictures somewhere, many people can take a look. 😀 What mistake did you make? There might be residual damage.

I spotted this ELV PCT-7000 PC-card-tester on my local auction site. Not sure how useful it is for me, and I need to find the documentation (still seems to be available from ELV)... Still a cool thing to have and I did not pay too much. https://at.elv.com/pc-karten-tester-pct-7000-teil-12-203295 …

(double post because of 5 attachment limit) Also sort-of-retro, since it seems I will be working at home for quite some time, I had to upgrade my home office/retro man cave a bit. I moved my work desk to a different corner in the room, and found an IKEA Jerker desk as a new work bench for the old …

There is certainly +5V and -12V elsewhere on the card, I can measure them on Pin 4 and Pin 11 of U11, for example. However, there is still no +5V on Pin 14 of U12. There is +5V on the +5V side of R38, but the side that is connected to Pin14 shows no voltage, it is shorted. When I remove the DAC at …

Ah, good job! Did you take time to figure out if it was U2, U8 or U16? So there were (at least) two separate problems. As for you PCM distortion question. I don't know.

Actually, sounds just like mine. It does not have the crackles like the OPL2 or the distortion of the PCM audio. Well.. I'm not familiar with how CMS sounds, I guess it just sounds metallic/distorted due to being limited to square waves or something? Regardless, I'm looking at the schematics and I …

CMS is the same quality as OPL2 music? Also with more distortion on the left? I added a recording of Monkey Island in CMS mode: https://drive.google.com/drive/folders/1AWtnFMgwHpkFFN9T56XP-YktpK_z5vqX?usp=sharing As far as I can tell, yes the distortion is there.

That does not sound right. Music is okay but PCM is broken.

If you're going that route, also try U4 if you have one (EDIT: a spare). My broken TEA2025 sounded like this: https://www.vogons.org/viewtopic.php?p=822621#p822621 After a couple of weeks I had time to look into the issue with this card.. I am now trying it in mmy 430TX Pentium 200-MMX system …

Hard to find, but we can still try :) Whereabouts did you live then? Europe, USA, elsewhere? Is the black rectangle in the middle a drive (5.25" slot)? And another slot above it? Is there anything to the right of those drives? Maybe a 3.5" slot on its side? EDIT and you can browse through this …

Well.. How about CMS? I haven't tried this yet. So here is my question: What is a good game to try CMS sound on the Snark Barker? If CMS levels are on par with FM then I know the issue is not FM being too loud.. Which would be a weird twist. Paku Paku is easy and free: https://deathshadow.com/ …
