If the goal is preservation, it would maybe be better to preserve the original GUS (GF1 chip) because that one is more essential to run demo’s. And maybe reimplementation would also be a good idea because Interwave chips will not be around forever.

Yes I think the ultimate goal would be a fpga version of the GF1, hopefully one day someone with the talent and interest can do this.

Does anyone have more information on the Am78C201 besides the simple pinout document that can be found everywhere. I have seen references to some Programmer's guide as well. And other documents I should be aware of?

The Interwave DDK (Driver Developer's Kit) and SDK (Software Developer's Kit) are also in the wild.

I think that's about it, but it's been a while since I looked.

That was incredibly helpful. Thanks a lot!

Alright, I suppose not. I started designing my own board.

I'm not sure what type of board you plan to do (which ram etc) but the Gravis deserves to be an available card and open hardware with files that can be developed further. I feel like this is an important thing for the future of the demoscene and preservation. These photo's of the Gusar clone might help you along the way. I wish I had the original Philips board to scan but I don't (yet, am trying to buy one) right now none of the clone can be bought. so.. go forth

Hi and thanks! This might actually be something that I could work with.

No problem, I hope they are good enough, let me know if not. The board (and photo) is 163.9mm x 100. If you get your design done and on github let me know also, it would be great to see it out there.

Didn't some russian guy already made GUSAR that was basically an IW card initially cloning Argus and then moved to their own design?

Isn’t it Still the same design ?

He has the GUSAR light which seems to be much the same as a Philips card I've seen. But yeah we are several clones deep by now. The problem is you can't actually get hold of any of them.

Hey, do you have the BOM to these boards as well? And if you could take even more high-resolution images of the boards, that would be great. It's quite hard to see some of the part markings.

Don't matter the images, they are good enough. But what about the Bill of Materials? Do you have that too?

The BOM is already mentioned in this thread plenty of times, here's the link http://bit.ly/2Ddf89V. I can help you with close ups of some numbers on the board if you can't make them out.

That's the BOM for the Argus, not the Gusar, isn't it? Or is the Gusar just a subset of Argus so that the BOM applies to Gusar as well?

They are both clones of the original and each other

Aha. I thought the Gusar was a smaller version of Argus. My bad.

I haven't been on Vogons since April, what's the status of the Argus?

eeguru from the vcfed forums is actively making just such a thing. You can have a look here for more info, the video is pretty long but interesting. :

It's gone rather quiet on that front though.

I'm finally getting my own card courtesy of someone on ebay selling this for a reasonable price. I never thought I'd find one. This thread has been great for figuring out how I could put 2MB of RAM on there instead of the currently empty 512KB RAM footprint. Really hoping it gets here in one piece and actually works:

Many thanks to shock__ for sharing some of the prototype pictures - this one here confirms that it's possible to get a 42pin soj working on the 40pin footprint as long as those extra address lines are hooked up without shorting VCC/ground:

It's kind of rekindled my interest in having a go at making my own one though, the chips can still be had internationally for about $20. There's enough info in this thread for the now no-longer-available gusar to have been made to a reasonable standard. Personally I'd like a combo OPL3-SAx & GuS if it's possible, kind of like a Gus extreme. With the pin density of the SMD chips, it would be worth learning how to use solder paste + stencil.
Also there are now quite a few cards I can look at for reference that aren't a GuS, there's this cool 8-bit ES1868 sound card: https://github.com/hkzlab/ES1868_ISA8 and some PC104 implementations of the later 'all-in-one' ISA soundchips like this one that rasteri shared after making one for his tinypc build 😀 : Open Source PC104 Soundcard
