Seems like fun, but no.
I meant real physical PDP-11 (I can't remember if it was a 45 or a 70) with
tape drives various RK05 and a weird disk subsystem that presented as 4 *
RK05, and about 40 or so cheap VT100 emulating terminals. Also there was a
GT/44 (I think that was the designation it was a rack mounter PDP-11 with a
14" vector graphics display very suitable for playing Lunar Lander).
Octal was clearly the correct number base for all systems programming using a
Then we got a VAX-11 750 with three 20Mb drives (that looked like top loading
Huge upgrade as hexadecimal became the one true number base for all systems
It is left as an exercise for the reader to deduce or even infer why octal and
hexadecimal were so important in these different cases.
