I think you've mixed me up with someone else. I was never out in Ohio. Joel flew out here to Burlington, Vermont for a few days and we worked on it here.

All: Steve's Z-80 code did the hard work of coordinating disk I/O, cache access and DMA. In contrast, Andy's and my 6502 drivers only had to set up a parameter block and tap an address line. Well, and juggle four operating systems!

Much as I'd like to take credit for the on-board firmware, I was not the person who did that. I was involved only with the Softcard and Applicard CP/M drivers and setup utilities. A fair amount of work, but not on the scale of the on-board stuff :-).
