   I was talking to Holger about the first PC he used was a Sinclair ZX81,   
   and I was thinking out loud that they sold a ZX80 PC too, and found out   
   that I remembered it correctly.   
      
   But You talking about the Z80 CPU in the C=128 brought a memory back to   
   me.   
      
   Rodney Zaks wrote a book called "How to program the Z80" @ 1980.   
   I was in a Radio Shack store in 1984 and seen the book Marked Clearance   
   and bought it thinking I'd learn some about CPU's from my reading it.   
      
   I didn't, but I kept the book for reference.   
      
   RS priced the book at $10.95 USD.
