I mean, really? None of this theory stuff. It's extremely compatible. I used it for about a year, before moving on to 68020s and so. The two main potential problems are with MOVE SR, and in handling bus error exceptions wrong. I don't know of any program using bus error handlers other than SetCPU, and in fact never ran into a program that didn't run on the 68010, so I suppose this is more of a theoretical concern. > 2) How well does the deciGEL program work? DeciGEL completely solves the problem in the Motorola supported way, by handling the exception. This works great unless you're loading something that requires you to reboot the machine, at which point DeciGEL is lost. There is apparently an execption handler that'll install itself as a RAM resident module that survives reboot, so perhaps there is a complete fix. I've solved the problem myself by avoiding any software that requires me to reboot my system. > 3) Where is a good place to get one at a reasonable price? Don't know where, but if you pay more than $10, you're not getting a good deal. The 68010 will give you at most maybe a 20% peak speedup, though I think it's probably more in the 5% range typically. > 4) Can somebody with a 68010 please report on the success or failure > of the following programs: > Excellence > Tetris > VLT I've run VLT myself and seen Excellence run on a 68030 machine, so I'm certain they work on a 68010 machine. The PD version of Tetris I have works too; not sure if they all do, there are so many versions around these days. Try Blockout (California Dreams) if you like Tetris, it works on all 680x0 Amigas. It's a really cool 3-D Tetris-like game. > Mike Conca, Computer Science Dept. * conca@handel.cs.colostate.edu -- 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
