Message: [QUOTE="pigpen02, post: 625408, member: 23859"] Post was a joke (note smilie) for old time computer people, and those who actually had seen the chips, so I guess it was pretty obscure. Sorry. K is for kilo (1000). Those are very old computer chips from the time I used to build computers. 256k chips held 256,000 bits. Nine put together to make 256k bytes (8 bits plus a parity bit for each byte). 18 on a 512k (kilobyte) motherboard; 18 more 64k chips to make the FULL 640k RAM that was all that was addressable at 4.77 megahertz. Later motherboards could address more and used 512k and 1024k chips. The chips came from Singapore and Malaysia among others. Now, my computer has 960 MB of RAM at 2.8 gigahertz, or 2000 times as much memory (500 times as fast, too), and it is not on 72,000 little chips. Now SIMMs pack mucho memory on a little board that fits into motherboard slots. We have come a long way from 8k memory computers (DEC PDP8, e.g.) that took up a whole room. [/QUOTE]
