TSS at CMU was extensively rewritten in assembly and became quite tolerable--hosting 30+ interactive jobs along with a background batch processing system. When I arrived in Sept 1975 it was quite unstable with up times less than 1 hour. 2 years later it would run for weeks at a time without going down. As I understand it* most of the changes were simply getting rid of things that were not present on CMU's 360/67. (*) was told by someone who should have known circa 1974 who also worked in the machine room 3rd floor in what became Scaife hall.
