So if I read that correctly, all parts can be ordered, except the PCB, the volume wheel as well as the bracket.

In addition to that, you need either a "44-PLCC to 40-DIP adapter" together with a "SB 2.0 DSP chip from China"
-or-
buy a blank Atmel 89S51 (as listed in the BOM) and program it?

I am a bit wary of joining one of the order lists, as I would like to know whether I would be able to successfully assemble this one, or whether I will have to stop at one point, missing some kind of rare chip or part throughout the way...

All the chips used in this design are pretty commonplace.
Paradoxically, the most problematic part to obtain (for me) would be the quad-timer IC NE558.

1The Firmware
2There are two ways to get a programmed 80C51 chip for the Snark Barker. One is to purchase a SB 2.0 DSP chip from China and put it in a 44-PLCC to 40-DIP adapter. This works fine and provides the largest feature set.

4Another option is to buy a blank Atmel 89S51 (as listed in the BOM) and program it with this HEX file.

what is this "SB 2.0 DSP chip from China" , anyone knows?!
also added my self on that sheet 😎

So I was looking up the difference between the SB 1.5 DSP andf the SB 2.0 DSP and here is what I found:

While the v2.00 DSP added auto-initialize DMA capabilities to the SB1.5 (a good thing), the Sound Blaster 2.0 shipped with DSP version 2.01, which additionally features higher playback and input rates (via the high-speed modes).

On this thread:
Sound Blaster 1.0 worthwhile?

The DSP differences are also outlined here:
http://nerdlypleasures.blogspot.com/2010/06/i … d-blasters.html

I would also like to know what to look for but I guess I can go through my SB 2.0 cards and find the chip part number there as a google search is not coming up with anything.

^ the issue is not the chip part - the issue is what we don't have the SB2.0 firmware to burn on it
it will be the same mcu as the SB1.5 AFAIK
really wondering what chinese sellers have SB2.0 mcus...?!

well mame has in it the sb16 rom. maybe they have a 2.0 rom as well?

Nice work, mate!

Sorry, I thought I was sufficiently clear: not my work, it's the work of "Tube Time"/schlae.

And yes, alternate names for this include:

SNOOD BLOOBER, SOUND BLUSTER, EAR BUSTER, SNART FARTER, SNUD BLUFFER, SNARD BLARGER, SNEED BLEEPER, SNORP BLORPER, SNOT BLOTTER, and SNOOT BOOPER. 🤣

I ordered 10 PCBs at JLC. Will take some time due to chinese new year. Will contact the interested people once the PCBs arrived. Will be around 11th Feb, most probably.

I'll be following this thread with interest 😀

Thanks, will be expecting your contact. Feel free to PM me here as well, I'm not big on checking email unfortunately, I could miss your mail 🙁

I sent a message to the tubetime bolg about the SB2.0 chinese DSPs , seems it's in moderation queue or something... I hope we get a reply!

Would it be possible to dump the code from a SB2.0? Or are they read-protected? Would be nice to be able to upgrade the card later to 2.0 capabilities.

possible? yes
easy / cheap? nope....

Please share the info here if you get an answer back 😀

+ I cant find it anymore, but I remember reading a post on MAME/MESS mailing list? or some forum about guys running chips thru decapping/dumping service and there was a talk of already obtained SB 2.0 and 16 4.05 firmwares.

Edit:

ct1741_v413 hanging note bugged, common to SB 16 CT2230/AWE32 CT3990

Me too!

If Cyrix200+ is OK with it you can ship my board to him too to save on shipping, I live close by so can easily pick it up locally.

I don't mind. As I said: German Post probably won't take the PCBs anyway, so I will most probably have to opt to DHL or Hermes, depending on how much people want to spend on shipping.

Yikes, DHL and Hermes are rather expensive.. My friends in DE can actually ship sound/graphics cards to me in bubble envelopes via DP Standard International, please do first check if that really is not an option. Cheers 😀

Also, just to make sure I get the ongoing conversation right: Every component on this card can be found online? As I understand only the DSP BIOS chip is difficult to get and needs to be programmed? Can anyone here volunteer to program and forward the chip to me if I order one to their address?

Ok, I have put up a Google sheet:

I have added my name in case someone backs out.

DP won't? I've received enough complete cards shipped as 'letter' via DP, these PCBs are flatter so should be no problem.

That said, where in DE are you located? If costs get prohibitively high I might just drive over to pick them up 😉
