I have run A2052s, A2058s, 8-UPs, A2090as, A2091, and Hardframes all in various combinations together, in the process of bringing up the A3000, and they all play together fine. If the GVP doesn't work with the A2090, I would suspect there's a problem with the GVP. That doesn't mean there couldn't instead be a problem with the A2090, but since it has worked (as well as A2090s work) fines for you so far, that seems like a rather slim chance. The A2090 does have it's problems with the system, but its bus timing is generally very good and quiet. >Should I be worried that the GVP card will interfere with other cards in the >future. I would be concerned about it. Perhaps GVP knows what's happening here. Strange thing is, since Jeff Boyer, the A2090's designer, now works for GVP, there's a good chance both cards were designed by the same guy. So in either case, it sounds like a Jeff Boyer question to me l^) >Brian Waters !{iuvax|pur-ee}!bsu-cs!jbwaters -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "What works for me might work for you" -Jimmy Buffett
