The PERQ one is POS (no slash, no lower case AFAIK). It's pascal-based,
much of it is written in an extended pascal. The machine code of the PERQ
when running POS is somewhat like the UCSD p-code, although the OS is
very different (it's command-line based, in fact it feels a little like
RT11)
POS (PERQ OS), wirtten in Pascal (of course). PNX
(PERQ unix) was not
suprisingly written in C, though
Just how many "POS" OS's where there? I wasn't aware of this one, but
knew
about P/OS (stripped RSX-11 for the DEC Professional), and pOS for the Amiga
in the late 90's. Actually, What is an OS? Do the BASIC
interpretters with buit-in
keyboasrd, video display and mass-storage handling count as OSes? I could
certainly argue they are...
I would definitely argue that BASIC in my Commodore 8-bit systems is an OS!
