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! In a message dated 11/30/2015 12:03:12 P.M.

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. -Rick
