My roommate has played with the Atari1 emulator on his 2000 (1MB chip) with a Microbotics 8-UP (with 2MB installed) several times. 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... Therefore anything higher than an 68000 thinks it's passing instructions to a co-processor. Atari doesn't have a 32-bit bit machine (except for the new TT which is incompatible for this reason) because of this. I'm sure that this is because they never planned on _using_ anything higher than a 68000. Remember that AmigaDOS 1.0 (and I believe 1.1) used the MOVE SR, EA instruction, which also chokes 010's and higher. Sometimes people don't think ahead. The Amiga was never really expected to get this far by Jay Miner & the guys. They wanted a really hot game machine, not a multimedia/unix workstation. Of course, the IBM was never expected to last this long. Heck, the original Macs weren't supposed to compete with the Lisa... [And to those wondering, I mean the _real_ use of the word hacker above, as in _programmer_. The "Cuckoo" who wrote the book doesn't know what he's talking about, and we all know how the media can't get anything straight.] >-- >"NeXTs are useless... Mac's are irrelevent.. IBM's are futile.
