Since I've been curious about ISIS for some time, I was glad to finally
borrow a copy of the _ISIS-II System User's Guide_. Comparing ISIS to
CP/M is quite instructive. I already knew that CP/M has a few design
flaws which ISIS lacks. On the other hand, I was surprised at how much
memory ISIS takes up. And ISIS has its own design flaws (things are fatal
errors that might be recoverable in CP/M, disk formatting can be quite
complicated).
Does anyone have details on the monitor, ICE80 (simulator), UPM (PROM
programmer), or PLM80? I have seen the System/360 version of PL/M but
I didn't realize it ran _on_ the 8080. (The manual implies that it does.)
Having a system that can develop its own software is important, I would say.
(Yes, Tony, we already talked about the front panel and monitor on one of
the Intellec systems, but I think this hardware/software is different.)
