FWIW, some HP HPIL peripheals used a related chip
(3870). IIRC, the 82161
tape drive, 82162 printer, 82165 GPIO and 82166 converter all used said
microcontroller. The 82164 RS232 and 82169 HPIB used 8049s, the 9114 disk
used a 6809 (!).
I don't think the 9114 using a 6809 is all that unusual; other
91xx (and I think some of the 794x) devices did that too.
