I've got GVP DSS8+ "Digital Sound Studio" for sale. It's got a clear plastic case. What's it worth to you? Hopefully, 200 million dollars. Wow, I say. :-) But, I'm willing to let it go for significantly lower.
If I find the software for it (if it had any) and manual, too, I'll throw those in. I got this item with a load of Amiga stuff and don't need it and can't test it. It looks like the previous owner didn't ever use it because the connectors are all shiny. I can't even see any dust inside, through the clear plastic (see above).
PMail me. I'll stick a picture up on my for sale site when I can, which may not be soon.
edit: Will trade for an A520.
edit: I found the disks. Install and Samples. Do they work? Let me know. :-)
