I had some progress with my HardSID clone. I have completely redesigned the power supplies (there are a surprising number of different voltages involved!) and amplification circuitries. Hopefully this makes it a little less sensitive to noise than the original. It's just a prototype with lots of …

Thanks everyone for the kind words here. I created this thread quite a while ago and then forgot about it after no one commented for a while. Strangely I didn't get any notifications when people actually started replying. By the way, Retro Erik on YouTube will review a few of my cards in the near …

I'd like to get a parallel port sound card to use with a couple of thin clients that I have. Could someone clarify how many games would be supported with the Covox/Disney device? Would I be correct to go off of the Mobygames lists for these two devices? https://www.mobygames.com/attributes/ …

Quick question. What DSP version is flashed on the Soundblaster 1.5 clone? To answer my own question, SBDIAG reports DSP 2.02. So this card is technically a SB 2.0? Haven't tested any 44khz sample rates yet. 8-bit 44khz wav files play fine! I think I read somewhere that functionality-wise the only …

It should be rather easy for someone who has the actual board to measure where RA1_2 goes if this is the only question remaining. Is anyone up for it? Perhaps Shponglefan wants to have a go at it? David

In this photo, it looks like a wire is connected to pin 2 of the RA1. RA1-2_2.jpg I'm assuming that pin pin 2 of the RA1 is connected to pin 13 U5. This doesn't make sense, however I can't explain the wire I've marked red in the picture above. Can anyone check if this is true? Hi sgc! How's it …

I'm terribly sorry, but apparently I might have missed some of you guys' email! :-( I just checked my spam box, something which I rarely (if ever!) do, and for some reason some of you that have contacted me about boards had ended up there! Stupid Google! I have contacted the two of you that I found, …

Woohoo! I finally got a new batch of boards. The four of you who have contacted me about the boards will receive their boards shortly. I also have about ten or so boards that are still unsold if anyone else is interested. david.e.larsson, and at you know, the very common mail domain of that large …

Nice to see more and more InterWave boards popping up :) ARGUS gerbers delayed once again (as always) ;) I know it's basically a 5 minute job, but kinda stressed out in another aspect of my life and I don't wanna upload junk.

Oh right. The only problem I have now is that I don’t have an IW78C21M1 or a dump of it. Is anyone willing to part with either? The Chinese sources seem to be completely out of stock now. The boards seem to work well without it so it’s just for completion. Some people still might like it to be there …

Hi! I just soldered a few of my own reverse-engineered boards that I posted about months ago (more like a year, actually). Someone posted pictures of a board (GUSar?), and I went full retard and reverse-engineered and fixed it up a bit. Some address pins of the SIMM were switched and some other …

I just realized that the sound in that video is really bad. Must be compression somewhere. Or maybe it's just the internal speakers on my laptop that sucks. It sounds better in real life. I promise. :) I had a look on facebook to see if you posted the boards in any group I'm in but can't see it. …
