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.
