Hi am looking for an hp 85 cpu
I have been hunting the net , in hopes of finding one ,
am also looking for an HP 85 service rom 00085-15006
the cpu was made by capricorn , lots of differen't definitions
or the cpu on the internet.
is there possibly a modern chip that could be used in place of it ?
any help or information would be appreciated
thanks

No, the CPU is _called_ Capricorn. That's the HP code name for it. AFAIK
it was designed and made by HP.
or the cpu on the internet.

Unlikely. It's got a strange instruction set, strange logic levels (6V),
and even stranger clock signals (4 phase clock at 12V levels IIRC).
There's nothing that will drop in in place of it.
