somewhere i have an edu system book.
HA! yea the fixed head drives made better swapping media! for tss 8
as core was small in those days!

I'd *LOVE* to be able to have a real-hardware HP Timeshared BASIC system
running here, but alas, those are a lot harder to come by than DEC
stuff. I do have a 2000/Access system running under SimH hooked
directly to an ASR-33, which emulates the experience relatively closely,
but there's nothing like the real hardware. I cut my teeth learning
programming on the HP Timeshared BASIC systems starting in 6th grade
under the 2000C version.
TSS-8 was indeed a timeshare system for the PDP 8, but it was written to
run on DECs earlier fixed-head disk drives that are hard to come about
today (compared to RK05's). I've heard that someone had made changes
to TSS-8 to get it to run on an RK05, but the fact that it's a moving
head disk drive versus a fixed head drive that TSS-8 was designed to run
under, the poor RK05 gets thrashed pretty hard when timesharing.
There are also the Edusystem timeshared systems that DEC developed for
the PDP 8, but I haven't looked too deeply into these yet.
