PnP ready Opti chip, the Unisound driver should be fine.

unisound can't detect card.
I have three cards with 82C928 chip, and Unisound doesn't see any of them.

Hello everyone. I am looking for any information and drivers for the sound card.
I will be grateful for any help.

Card specs... https://web.archive.org/web/19990501204252/ht … 0/pnpscsi2.html

Listed drivers haven't been archived, and can't find elsewhere atm... https://web.archive.org/web/19990219114243/ht … 0/software.html

No, the 928 (=MAD16) isn't supported, just the 924/925 in PnP mode and 930 onwards.

There are drivers & init tools for it here. But which OS are we talking about here?

If you want to use SCSI, you need to get Future Domain drivers for the controller. The empty sockets look like a boot ROM socket for SCSI and a supporting bus decoder 74-logic chip.

That Crystal chip is interesting. I'm pulling blanks on any searches for "21-01418" or "ATS 620Z84"- but take a look at the traces on the PCB. It almost looks like nothing is connecting to it and it's just stuck on there for show...

It's a weird one! See this thread which has the box art for it on a related card, apparently it's a PnP controller: Crystalizer TidalWave32 PnP - US made ISA PnP sound card with Samsung KS0161q/KS0171-2M + SIMMS, Yamaha OPL3, etc
Makes some sense since the litte 8-leg serial EEPROM is located right by it and you wouldn't have that EEPROM on a non-PnP card.

Looks like all the specs and chips match up, I think Crystal Computer Corp weren't around long and weren't very big (check out the typos in the specs section) so finding drivers might be a hassle if it requires special software to initialise. Very awkward also that they chose a name so similar to crystal semiconductor, makes searching for drivers much harder.

edit: best chance for drivers would be contacting MN Moody or DW12, I think the company was defunct before they ever released drivers on the web and they don't seem to have been archived yet. But maybe even that wouldn't work, the soundchip is different.

You sure that is the same chip? It has the "620" and "84" (maybe a Zilog Z84 microcontroller?) but otherwise looks rather differently connected (i.e. not directly to the ISA bus). Same 8-leg EEPROM though, so sort of makes sense. If so, this could be a real challenge in terms of driver/init.

Kind of guess work on my part 😀 I know the 82C928 is not a PnP chip and from what I recall also is not really compatible with Windows 95 particularly, so advertising it as a PnP card suggests to me that the Crystal chip is doing the interfacing. Along with that EEPROM being close to it.

We haven't seen the back of the card and that socket is possibly a through hole type rather than an SMD one so it's possible that the signal routing is done around the back of the card.

They describe that chip on the spec sheet as "Crystal Computer CC3000 Custom Plug and Play ASIC " so maybe the chip on the other card serves a similar function.
