>Can anybody tell (email) me what the CPU is in HP-87 computer ?

The processor in the HP-87 is a custom 8-bit CPU designed and built by HP
specifically for that computer, as well as the HP-85 and HP-86 (a CMOS version
is used in the HP-75 portable computer).  It was optimized for BCD computation,
which it does extremely well.

HP can provide full documentation for the processor as well as an assembler and
machine language development system.  For information you can contact Technical
Customer Support at 800-858-8867; they have a charge for technical help but can
probably direct you to a free number for more information.  You might also try
1-800-FOR-HPPC.
