[HECnet] Another TOPS-10 DECnet problem

[Robert Armstrong]

>You had a 20 that would handle 600 students in 1977???  

  I think he said something about six 20s…  I’m pretty sure there’s no way one CPU would have handled 600 timesharing users.   We could get to around 120 on a single KL10E with TOPS-10 before it got unbearably slow.  With TOPS-20 on the same hardware we could only get to 80 or so; TOPS20 was something of a pig.
