I havent heard about those folks since 1982. I was just starting to work
at Diablo Systems. We tested Daisy Wheel printers with a Multibus based
system and so we all had Intel MDS system in which to build code on. We
did have one Zendex based system. It held it's own among the crowd. They
all ran Isis from which we built 8085 and 8086 code. We programed the
8085 in assembler and used plm-86 for the 8086.

Ahh the memories (16K if I remember correctly)
