Hi Jerry and the list,
Unfortunately, it's been back-burnered for now. The key factor in
deciding to postpone work on it is simply a lack of documentation.
There was far too much guesswork involved in the emulator. If only I
had some kind of description of the architecture -- even a block
diagram that included interrupt sources would help -- I think I could
have made it further.
As it is, it almost half boots. Not bad for pure guesswork and reverse
engineering from SVR3 source code, but not good enough to be usable.
