Gerbers are here:
Have fun 😀 If you need AM78C201AKC chips, I have some listed on eBay Germany.
Looks like inline attachments are broken ... check the post, both files are there and can be downloaded.
Gerbers are at the bottom of the post, documentation in the middle.
Stock has been sold out, gerbers will be released within the next few weeks.
I also have some InterWave stock I'd love to part ways with.
synoptic is now taking pre-orders for North and South America ... you can place orders on his website:
keropi is accepting pre-orders for Europe ... orderss can be placed here:
No pre-orders and ooops ... I guess the "few months" have been almost/over a year again.
I'm currently meditating some alternative roadways since -i want to be honest there- this project has been a crawl since forever and I don't exactly see it take off any time soon - if someone wants to take over the production and logistics at a small margin (we'd define before hand) and can prove to be trustworthy I can see a run still happening, otherwise not so much. This is mostly what has been holding me back, this is certainly something I didn't see when I originally started to project, apart from minor personal things. I know it's a pretty crappy deal, tons of unpleasant work & responsibility, basically for free ... but a warm fuzzy feeling in your stomach that might be a one time chance to go into Gravis UltraSound history?
My current idea is to release the gerber files for production (with an explicit wish/silkscreen to remain financially accessible [instead of "non commercial"]) and sell off a larger quantity of the remaining stock I have and keep a limited amount for myself. Previous donors/supporters will have the option to have their remaining credit in InterWave ICs shipped (just shipping costs need to be covered) or get a 25% refund of their donation if they wish (afterall pretty much all of the donations has been used up and I made no money from this). Any input?
Also hoorj (I guess), this project got its' own video on LGR today.
Current status: This project is closed to previous donors for now - No exceptions, no need to ask via E-Mail/PM or the like.
A first batch of the final run has been produced and is being delivered. More batches/orders will follow within the next weeks/months. Keep watching the thread for updates - at worst you will be contacted (you won't lose your slots)
Documentation (partlist, component map, BOM, installation notes, useful programs, etc.) for the final run:
Just thinking at the moment ...
I have one of those lying in front of me ...

Which can be made compatible to classic GUS cards according to gerwin's post here by adding 512kb of RAM in the intended solder footprint.
EC251 InterWave Audio Card
Might also be possible to easily boost it to 1MB.
AM78C201 & IW78C21M1 chips can still be bought as NOS from China.
Seeing how above card is a 2 layer board, it could be produced cheaply as well (~$20).
Considering GUS cards go for quite a bit these days ($80+ last time I checked) it might be possible for one to solder one's own card for maybe $30 (assuming the custom chips don't cost an arm and a leg from china).
As usual with my projects, I'd reverse the schematic, draw an example PCB layout and produce a prototype and release the files once the design is confirmed as working (I _hate_ distributing stuff) so basically anyone with soldering experience and patience to go through acquiring all parts could build his own card.
What's you guys' and gals' opinion on that?
EDIT: development blog here: ARGUS Project thread - Now with gerbers and documentation in initial post!
Current Project: new GUS PnP compatible soundcard
