Dude, in my day no one in the freakin' Computer Science department even had email. At least until sometime late in my second year when we got some machines running Unix and Bellovin, Truscott, and Wright were putting Usenet together. I mean, one reason I picked my dorm was that it was one of two which had card punches and a machine that'd read the cards and send the program over to TUCC for batch processing. And we had to know how to write at least enough JCL to get our batch jobs to run...

Related to that, MTV has a show starting July 5th called "The '70s House" were a bunch of teens/20somethings have to live in a house with only 1970s level of tech and decor. I find it amusing in that MTV only dates back to 1981.
