Hey, this is the classic computers list, so you should only list early stuff,
(say pre-1990), and leave out all the modern crap (but I repeat myself).

So here's one I'm not sure anyone else will catch: TFTP has an email mode!
Why? Well, FTP is gargantuan (compared to TFTP) and needs a working TCP to
boot, so if all you have is a working TFTP, and no email...
