>Hardware probably. Code, I'm not sure. Mabye the code in assembled form 
with addresses of the cal tables.  This is a ways off anyway.  Right now I'm 
concentrating on the scheduler, insturmentation and SCI routines.  Next I 
will write the interrupt handlers for the refrence pulse and EST channels.  
Finally I'll do the timing algorithim (2D lookup table).  Someday EFI will 
probably be added since it is a simple add on at least as far as hardware 
and timer code are concerned.  I have the digital core schematics done in 
OrCad format but don't have a way to scan them.  The interface board is not 
designed but should be pretty straightforeward. I'm in the process of 
building a vehicle intent copy of the hardware.

when I get some time and get to a good stoping point in the code.

Of course, all responses are my own and should not be mistaken for those of
