Right, if you check the FreeBee site they credit several of their emulation advancements to "Jesse", who is the OP on this thread smile

lol, indeed that is me. My goal is to help get the UNIX PC running in MAME. Long term I'd also like to work on the Convergent Miniframe driver as that is a similar precursor machine to the UNIX PC.

You are right, I did a bad quickcheck there, it is the vme_mvme120.cpp by Luigi30 that needs 68451 MMU, I need a 68450 DMA controller for the vme_fcscsi.cpp! blush


Because I can

Might the HD63450 implementation suit your needs?
