Good to know. My PDP-8/S was stored indoors but my Straight-8

Nigel,
I first learned assembly on a straight-8. Also learned about repair with
the same machine (1974).
As for fun time wasters back then there was a DECUS paper tape that could
compute n! up to 200! exactly. I remember that I could start it before
lunch, come back, and then about 15 minutes l

Brings back memories! My first 6800 cross assembler came to me as 2000
Fortran source code punch cards. We had an F4R4 compiler on the PDP11
but the card reader was on the PDP-8.
The only common peripheral was paper tape. One night, the Chief
