Is there anything I >can do to the A2630 to turn its autoconfig memory into addmem memory? Unfortunately, nothing reasonable. The A2620 can remap its RAM with a PAL change, but the extra pins on the mapping PAL used in the A2620 was needed for more important things in the A2630. It might be possible to hack in something with cuts, jumpers, and a PAL programmer, but you won't get it easily. >I can live with addmem, and I can live with a solution that I'll have to undo >down the road when I slap a 64 meg daghterboard on the A2630 :-), but I cringe >whenever I think of that wasted 4 megs just sitting there dropping in value >every day. I have a number of interesting A2630 hacks in the works. If I do come across any easy way of doing this, I'll certainly post it as well. There is definitely no "plug and chug" solution. >Ed Hanway >Eastman Kodak Company ...!rochester!kodak!elmgate!jeh >#include jeh@elmgate.UUCP jeh@elmgate.sisd.kodak.com -- Dave Haynie Commodore-Amiga (Systems Engineering) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy Too much of everything is just enough
