Speaking of interesting 8080/z80 operating systems,
anyone out there on the
list besides me (and the two people I mention below) ever play with Ed
Ziemba's MARC operating system (very Unix like, for the 8080 - but never
published, because Ed Ziemba passed away in an unfortunate snorkeling
accident)
I still have some copies (the latest being the CP/M hosted/"parasitic" boot
version B.9 and root file system B.3), and some paper documentation.
