Errm, the PDP-11 was TTL integrated circuits <http://hampage.hu/pdp-11/1120.html> and LSI later.
Back then (1970's) TTL and ICs couldn't handle high current. TTY driver and disk interfaces were transistors, and even the boards that were TTL had a sprinkling of transistors. TTL simply couldn't handle those currents and voltages.
It certainly had networking - it was one of the main targets for interface boards - and there were plenty of glass teletypes by then.
Unix V5 (in the 70s), as well as V6 and V7 into the early 80s, didn't have networking capability. I first met IP networking on the BSD2.8 versions on the 11, though there was some point-to-point over serial links and of course UUCP, but not what we think of today as networking. Also the books are wrong about IP networking coming in BSD4.2, it came in some versions of BSD4.1, certainly stable and useful in BSD4.1c because I loaded that on one VAX/780 while a colleague loaded it on the _other_ and we set up our first real IP network! That was "hcrvax",no longer just a UUCP node!
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!!
V5, which I admit I didn't use much since I was dealing with more pressing personal matters, was like the old CP/M, one program overlaying. V6 and V7 as well as many SYSIII and some SYSV was roll-in-roll-out. I suppose you could call that VM of a sort in that the whole aggregate of running code could exceed physical memory, but each program had to fit into available memory and all were statically linked. No VM as paging. Paging had to wait for the VAX.
These people would never see the notice from CRON.
I don't know about you but I see my cron mail in the same way as the rest of my mail, using my MUA, Thunderbird in my case.
Because you, like me, have some geek in your blood (or you wouldn't be here) and have configured your system to do that. Ordinary Joe consumer, the kind who might buy his netbook at Wal-mart or Sears, should they offer it, isn't a geek. Don't expect him to be able to dig under the hood with a command line. Microsoft have done a very good job of brainwashing the world into expecting everything to "just work" and be configured via a GUI. -- Indeed in nothing is the power of the Dark Lord more clearly shown than in the estrangement that divides all those who still oppose him. --J.
