Ward has "retired" from the VIC-20 digital archaeology project, but 
there is some work going on.  The PCB scan in Micro,

I'm including the rest of your message verbatim, for the reference of 
the digital archaeology project list members.  (All VIC-20 enthusiasts 
out there are welcome to join the project!)
