I assume the parallel card that you reverse engineered and rebuilt on GitHub has the same ROM as the one you've tested with the ESP? I built one of those (and have 4 spare boards) that I still have yet to properly test.
Does anyone here sell or have files for emulating a ProFile drive for an Apple Lisa? I have a dead Profile 5MB drive i'd like to convert over (doesn't go through full seek) but the two options I know of aren't the most desirable. IDEFile (or whatever) is pretty expensive and afaik isn't the best...
