Hi,
I also learned to program in Oregon Software Pascal II
(on a
decwriter hooked up to a pdp 11/70) so seeing a whole OS written in
Pascal (and assembly I bet) would be really interesting.
You should track down one of the Apollo DOMAIN workstations (c.
1981-1990). Their OS was originally written in Pascal, and in some
ways more extensive and robust than the Lisa OS (real VM, networked
filesystem, etc). Towards the end more parts of it (e.g., the TCP/IP
stack) were implemented in C as Unix began encroaching on it. By the
end of the decade, Unix was the only way to survive in the Workstation biz.
The DOMAIN OS sources were released outside of Apollo to certain
favored customers (we had a copy of it at our university). Apollo
was acquired by HP in the early '90s, so any official release would
need to come from there.
FYI,
