ISIS ran on the MDS-800, and probably on the 8080-equipped Intellec
8/80 before that.
The Intellec boxes definitely ran ISIS.
So, what was the first 8080 disk operating system? I remember the
guys at Diablo had put together in the early 70s a system that used
one of the Diablo cartridge hard disks with an 8080. They called it
the "Merchant", but the Xerox acquisition was happening around then,
so I'm not sure that it ever saw the production line. The
application language was supposed to be Diablo's own dialect of
DIBOL.
I did use the assembler they wrote for the system, however (ported to
run on our own OS). I still have a listing of an assembly from it
somewhere.
