Oh, yes - people still looking for a fast startup can relate to core memory. You switch the machine on, set the switches to the base address, hit 'reset', hit 'run' and you are up and running the last loaded program (CPU next instruction address registers etc.. are volatile, so can't be used) So, for example, set 0019, Res, Run, and you are up and running (CIL System 90, and others) Not too shoddy, eh?
Oh, er, when can we get a 5 channel paper tape reader, 8 cps (characters per second) teletype, 800bpi (bits per inch - cute, eh?) mag tape, and punch cards, please :-))
