Some friends and I have a pdp8 here.. we replaed the bulbs with leds
about 25 years ago, but
last time we tried it, it still ran.. model number escapes me.. its
currently at a friend's place.
It was the controller for a DISTEC (?) display, the predecessor for
the wonderful gt40 and used as a frontend for teh pdp10 (KA10, serial # 6)

Heh. I have a paper tape from my first year at uni somewhere in the
mess on my desk. It's been there for at least 10 years, and it's
short enough for it to be practical to read it in by eye, but I
haven't got more than a third of the way through. It's in FOCAL-69,
and does some world-shattering calculations like mean and standard
deviation. It would be fun to run it again--once.

Wow! Have not thought of FOCAL in years. Used to write a bit both
when in
college and, using FOCAL-11, in my early years at LLNL. Unlike
FOCAL on a
PDP-8, FOCAL-11 ran on top of DOS-11. (No relation to Microsoft
DOS.) The
PDP-8L was the only solid state computer in the lab. All of the others
still had vacuum tubes and drum memory, though the Univac Athena
had both
drum and core.
In college I wrote a simple craps game and, it it caught you trying to
cheat, it zeroed your account and gave you the finger on the
ASR-33. My
computer logic prof (and department head) saw that trivial ASCII
art and
chewed me a new one for putting code to generate that gesture on a
school
computer. That was about 45 years ago. Memories!
Brings back memories for me as well from high school. Back in 1972.
PDP-8/L in the Levittown (NY) School District.
