I think, if I'm not mistaken by the looks of it, it does it's job by completely emulating the rom. I'm trying to use a different approach with different hardware specs and with different goals. 8-16mhz attiny85 with bare minimum program flash along with 27c512 rom. - I don't want to (and I can't actually with that chosen micro) chase the individual cycles of rom accesses. - I'll not drive the databus - I'll only listen to 1 address bit - That address will be modulated so that receiver will understand sender is active and it's just not out of regular use of the computer (1st problem : pilot sequence) - Pilot sequence will be iterated until receiver is in sync with the sender (2nd problem : syncing) Much like the pilot sequence of loading from tape.
