   No.  I never had a Z80 based Radio Shack computer, just the various   
   Color Computers.   
      
   I think I used < "UCSD Pascal" "TRS-80"  > for the hits I got and   
   looked over briefly.  I was more trying to see if such a thing   
   existed.  You might do the search and look closer at what's out   
   there.   
      
   After posting, I got a bit curious.  And it looks like one   
   can get a p-code interpreter for Linux.  There again, it was   
   a brief search and I didn't read too closely.  But it almost   
   seemed like the sort of thing that would be available.
