Sounds like a nice addition for the archives.

Yea I think that's what Jack was talking about.  So your real H8 could use a 
PC as a disk.  What I was proposing for the emulator could be much 
simplerand faster - just a virtual i/o port that you write to when you have 
paramater/data block ready to be serviced, and another one to read from to 
tell you it's done (the latter only necessary if you want asynchronous

Can we add that to the archives also?  For those with real H8's, of 
course... I don't think we'd want to emulate that!
