I own an A500 with 512k ram mounted in the empty sockets on the motherboard. (hence, I have 1megchip but not an a501/clock) The Atari emulator said in the original german docs that it doesn't with without $C00 memory. Atari1 doesnt not work for me (gabage graphics screen then guru) the reason for this is that it tries to use $C00 and theres nothing there. (atleats I think) on my machine my extra 512k chip is at $80000. The guy who said he had a 68010 and it didnt work also said he had .5Mb of chip, and external expansion ram. This doesnt help, you atleast need a A501 or memory at $C00. (I may try to use a debugger to relocate all absolute references to $C00, but if its too much, i won't bother.) (I have an idea that the TOS may be copied to $C00 ram and then executed with absolute JMP. Ill have to check on that theory though.) So to summarize. Atari Emulator not only doesn't work with >68000, but it also doesn't work on 512k machines, or Non $C00 memory. -- "NeXTs are useless... Mac's are irrelevent.. IBM's are futile.
