Goi: That's right. I actually still have a GUS PnP sitting in my machine right now. The GUS was my favorite soundcard. Gamers had some problems with compatibility, but for the tracked music and demo scene, it was impossible to beat.
In an era when the SB Pro & 16 was the hot new card from Creative, Gravis had 1mb onboard sound memory, using patch caching to allow the use of a very good sounding 5mb set.
I remember how I bought my GUS in the 256kb version to save money, then cannibalized the RAM right off an old video card (this is the old days, where ram was actually housed in DIP sockets), and filled up all the free sockets to give me 1mb. Damn shame that gravis went under.. they had the same problem that Aureal went through : Great product, niche product, mammoth competitor.
