Back then you might have 30 or 40 users on a single PDP-11. I recall that well, and yes those old 16 bit transistor technology could handle 40 simultaneous users. No virtual memory, perhaps a total of 80G of disk. Good old Bourne shell. No networking.
Errm, the PDP-11 was TTL integrated circuits <http://hampage.hu/pdp-11/1120.html> and LSI later. It certainly had networking - it was one of the main targets for interface boards - and there were plenty of glass teletypes by then. I'm not sure what you mean about no virtual memory; I can't think of a machine of that era and before without some kind of virtual memory scheme. Unix ran quite happily!!
You're probably thinking of the PDP-8.
The PDP-8 used ICs too. At least the PDP-8i did. IIRC, integrated circuits made it possible to make inexpensive computers, such as the PDP-8. Those may have been RTL or DTL chips though. I't's been many years since I've worked on one, so I've forgotten many of the details. -- Use OpenOffice.org <http://www.openoffice.org> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
