TITLE XENIX - IO system to mimic UNIX
NAME XENIX
Xenix to dos file transfer?
Xenix ran on PDP-11 and PRO3xx as well as PCs.
"The system we used to develop Multiplan was
pretty sophisticated for
PC development in those days. We wrote the core product in C -- most
programs then were written in assembly or Pascal. We did our editing
and compilation on a PDP-11 running Unix. The C code was compiled into
p-code and downloaded to the target machines. We had to build p-code
interpreters for each microprocessor in use at that time."
I haven't put it up yet, but I have the proceedings for an early Xenix
developers conference where they talk about the PDP-11s running Xenix
that they use internally, and the bright future for the product.
Then OS/2 happened.
Multiplan and the original Word were two products that were p-code based.
My original request was for that version of Word. I was quite surprised
when what they released was the Windows product.
That explains a lot.
