   Was there in fact an 8051AH-BASIC?  I've worked extensively with 
8052AH-BASIC, and have never heard of an 8051 version.  The 8052 has 8KB 
of ROM, compared to the 8051's 4KB.  The BASIC interpreter filled...and 
I mean FILLED...that 8KB.  It's extraordinarily dense code.

   The Z8671's BASIC, on the other hand, fits in the first 2KB of ROM on 
that chip.
