Since I couldn't afford an IEEE-488 disk
drive, rather than just move
files back and forth on tape, basing it upon the cable and software
from a contemporary "Byte" magazine, I fabricated my own
nybble-with-handshake cable between the user ports of the PET and the
C-64, and moved stuff from one to the other over that.
You mean you didn't just make a simple cassette "null modem" cable?
I still have the 30 footer that connected my upstairs "play" PET to the
downstairs "work" one. Lots of people (especially schools)
"networked"
them that way in those distant days.
Until you mentioned it now, I never would have thought of it. Back in
the day, I never saw any articles in the journals about that, and
nobody at any of the user-group meetings ever mentioned it or showed
it off, but thinking about it now... I can see how it could work.
Just a passive cable? Do you have any special notes, or was it just
SAVE "FOO", 1 and LOAD "FOO", 1?

Simple as that. Out to In, In to Out, and ground; preferably shielded,
compatible with pretty well all models.
Type LOAD "FOO" on receiving unit, run up/downstairs and type SAVE
"FOO" on the other, using the alternate port on the unit that had a
"real"
cassette drive (2001 & VIC20 in my case, with an 8032/8050 and a
massive Centronics 101 printing boat anchor at the other end), then back
down/upstairs to play/work. Remember that an 8050 2FDD was around
$2000+ back then IIRC, so one was enough for me.
In the classrooms they'd have a "hub" (but I don't recall now whether
they
were passive or needed amplification). The teacher would tell everyone to
type LOAD "FOO" and when they were ready everyone pressed return and
the teacher would enter the SAVE. If anyone wanted to save their master-
pieces, then one at a time they could send them back to the "server" and
copy to disk.
Since Jack T had his beginnings here in Toronto, Commodore had a pretty
strong presence and when the province decided to put computers into the
classrooms most of them were PETs; 2001s, then 4032s and finally C64s,
although by that time Apples (and clones) were also becoming pretty
commonplace. That's also one of the reasons TPUG (the Toronto PET
Users Group) was so successful and in fact is still active today, not
to mention Jim Butterfield's (another Torontonian) considerable support
and contributions.
