My roommate has played with the Atari1 emulator on his >2000 (1MB chip) with a Microbotics 8-UP (with 2MB installed) several times. Explain the reason why Atari1 doesn't work with my plain ole stock Amiga500 with 512k installed on the motherboard (not A501) doesn't work with the atari emul. I have the original pre-release Atari emulator that came out 6 months ago, and in the European intro screen it clearly stated that it needs $C00 ram. My symtoms are 'Choose resolution, garage screen, then reset-lockup. (it stays grey screen) and the power light is flickering a mile a minute. If I hold down both mouse buttons the screen flashs white-grey, but thats all. I have to reset to get my machine back. >as for >68000 processors, the answer is simple: No. > >From what I hear (from an Atari hacker) the Atari TOS uses the line-F >instructions (which are set aside for coprocessors) for some type of system >calls...

Rj Mical said something like they originally wanted a game machine, but then they started making it into a dream computer. With tons of features. But when Commodore bought Amiga, they removed alot of stuff and released a buggy OS to get it out quick. > >Greg > >---------------Greg-Harp---------------greg@ccwf.cc.utexas.edu---------------- >AMIGA! // > // Don't you just hate those long signature files?
