Very impressive work! Yeah, an Adlib Gold reproduction would be nice. However software support wasn't great and the obstacles seem not worth it. But I always love to see more repro sound cards. 😉

Update:
In the past few days, I have been busy working on the board.
First I did some measurements on my AdLib Gold on the pin header to confirm my previous assumptions about the power supply. In fact, everything is as expected. I thought that actually (almost) nothing can break on my AdLib Gold when I test the module with it.
So I was brave, attached it and switched on the PC .... Believe me, I was so nervous the last time I wrote my final exam at university.. Haha...
I tried the AdLib Gold test program first because it includes a test for surround sound. So far, the switch for "Enable Surround" was grayed out. But not this time. And what can I say, the module works great. 😀

These are my first sample recordings of this module.

For a comparison with an original module I took the following recording from YouTube.

I can't really tell the difference.

Let me know what you think!

I think that I will order two units, and let's go for the SCSI addon module! I have already sent you my small archive on that, haven't I?

Thank you guys!

SCSI adddon module ... huh ... I think that was still on your to do list, hard1k? 😄
I think you didn't send me your archive for that module. But I would still be interested in what information you have about it.

I am pleased that so many are interested. There is currently only one prototype, but of course I have the parts for more modules.
I'm sure you're interested in the price, but I haven't thought about that yet.

Well, I don't have much, to be honest.
The idea is that the Adlib Gold prototype quite resembles the production card, the only missing part being the Z0538010VSC SCSI controller chip, the 50-pin header, and a resistor array as a terminator (I may be wrong here), look:

As far as I can get, on the prototype the SCSI chip is connected to the bus in parallel with (or via) YMZ263-F chip. So, the idea was to trace the pins of the black expansion header on the Adlib Gold, and to implement some schematics based on the Adlib Gold prototype design. Not much input data, sorry... I'm attaching the datasheets for both mentioned chips though.

Cool picture of the AdLib Gold 1000 prototype!
Okay I understand the approach. I think it could probably be doable, but it is currently not on my road map. But I keep it in mind, maybe in the future. Or near future, hmm who knows...
