At NCC - Anaheim, I bought John Draper lunch (I never exercised with him) for a
quick consultation about P-system directory structure. I added some P-system
formats into XenoCopy a week later.
I have a cable with two heads on one end and a rj45 phone connector on the
other end. On the two-headed side is a 25-pin ( serial female RS232 ?) and
9-pin (serial female RS232 ?)
The 25 pin adapter has a GEM95 sticker on it.
What was this cable used for?

Pascal was the language of choice over at Apple in the original MacOS
days, and as Mike has noted Turbo Pascal was popular enough on the PC;
it was more, I think, that the UCSD-style language-environment-as-OS
paradigm never caught on in the microcomputer world. Early consumer
micros of course had ROM BASIC, but once you got past that to a
reasonably full-featured operating system, there was no compelling
reason for it to be tightly coupled to one particular language/compiler
when it could just as easily treat compilers as Yet Another Program and
support arbitrarily many.
OK
This seems to be the one that the list choked on
(possibly due to special quote characters?

well, it wasn't quite a "rejected by DR". But, the culture clash certainly did
strengthen IBM's desire for CP/M alternatives. And, they DID cut a deal with
Softech/UCSD-Regents to have UCSD P-system as one of the original operating
systems for the 5150.
The "very different course" of the market going with CP/M and MS-DOS, rather
than P-System, was due to many factors.

Next they'll want silver oxygen free plated plumbing and sewage pipes in their homes. Silver plated toilet seats?

Why stop there? A truly dedicated audiophile would run new pure silver electrical wire through the walls directly to the breaker box.
Then you gotta upgrade to the breaker box that was disinfected from transient spirits through an exorcism, and then special 24K solid gold-contact breakers in inert nylon housings.

UCSD P-system could only allocate contiguous disk space. So a disk that had
become "checkerboarded" by writing and deletng files had to be defragmented,
using a spplied utility called "Crunch".
Was that adequately protected against catastrophes caused by interruption?
Softech and UCSD Regents filed trademark registration for "XenoFile", and
listed it as a product, but as near as I can tell, NEVER sent out any copies.
(February 1987, I went to the Patent and Trademark Office outside of
Washington, Dc, and researched some trademarks, in preparation for my trademark
registration)
They also announced a "universal disk format" for ALL machines, but never had a
clue about how to do anything compatible with FM, MFM, and GCR.

Bob Wallace (Microsoft's tenth employee) wrote the Micorsoft MS-DOS Pascal
compiler. He told me not to use the runtime library, which was also then
included with Microsoft Fortran, etc. Later, he left Microsoft when an
appointment became necessary to talk to billg, and formed "Quicksoft", selling
PC-Write (a significant player in "shareware")
Did not make it to the list, so I am breaking it up and re-sending it in
pieces

In the original 5150 launch (August 1981), the operating systems announced were
availability of PC-DOS and/or UCSD P-System, and CP/M-86 was "coming soon".
