NJB> PC. I am probably the only one here to have actually seen an old drum NJB> memory (albiet one sitting in storage in Room 100), or a mercury delay NJB> line.
NH> Drum memories, such modernities!!! How about coil-wound DRAMs, from days when NH> computers computed and not stored?? NH> First non-personal-computer I used in 81/82, had drum memories still operating NH> as virtual memory. Okay, I'm not as cool as you, gentelmen ;-) but this talks has made me remember that for a while I was programming a computer which had 1kb of memory and it was on ferro-magnetic. The funny thing was that it kept its contents even when switched off. I could come back in 2 weeks and the data/code was still there. So RAM == long-time-storage on that applience. It had two rows of digital indicators to communicat to humans and a tape reader/writer (running on regular moder tapes that are now being replaced by CD-s), yup a funny applience :-) BTW is ferro-magnetic memory == coil-wound? -Anton --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
