That's not where Alex is having the problem. The code you have there simply loads the 6502 BIOS and calls it's cold-boot entry. The host BIOS uploads the CP/M image to the Applicard and kicks it off. From what I gather, that's where the problem occurs. The 6502 goes into a loop waiting for commands from the Z80 that, in Alex's case, never come.
I'm busy re-learning the details for all this stuff. Used to know it cold, but haven't looked at the Applicard in about 20 years :-).
