have another old piece since seeing this post I went looking for - was once of the first 64 CPU from company called NextGen for the desktop market - I was involved in that whole thing back in early 90's... (might have been late 80's)
...AMD bought them out way back - a few from that gig would say that AMD got in-part the K7 technology (came out of many years later).
NextGen was out when just i386 was coming out - it was a x586 133MHz 64bit cpu (and motherboard) that ran dos/windows.
have bunch of old S3 PCI video cards and the sales order from NewEgg when I bought them too.... funny, used them, when upgraded put that back in the box newegg shipped them to me in.
copy of DOS 3 still, also have the board and cpu yet from my old packard bell 1MHz XT - maybe still has some sip memory chips on it.
Some of the old companies way back that could mail order from, like comark, USA Flex, Hard Drives International, Sprite, Memory and More, Infotel, Midwest Micro, and all them companies that comark owned that ended in mall...
...all before NewEgg and ZipZoomFly's (googlegear.com) time'
you know a company that has been around a long time is PCPowerandCooling - used to be nearly 100% women worked there and I think maybe owned way back in the 80's as well.
of course was really something when RLL and SCSI hard Drives came around, no more 5.25" Floppy dirves (3.5" too) - then came the coffee cup holders, or the other name for it, CD ROM Drive.
