Hey thanks, Jim. So that means I can mix 100's with 80's on the Supra? It does have a scsi controller card with mounted drive, but the mem sockets are
empty. Other than that, there's the toaster card and a tbc card, but I don't see any accelerator.
At 7.16Mhz, it's 140ns/cycle and 68000 takes multiple cycles to do a memory fetch. NOP instruction which requires one opcode fetch takes like 4 cycles (2 for memory fetch and 2 for doing nothing internally).
I did have this Spirit Tech. Inboard which had problems with RAM access and their tech support sent me a 68000-10Mhz version which got rid of the problem.
