Sent mine to the tip a couple of years ago, along with my original IBM 4.77Mhz, though I did keep the original 10mb Hard Disk (double height 5.25") for nostalga's sake.
First computer in 1974, an analogue 128 byte octal machine with Nixie tube output designed by a friend of my father. Followed by an Altair I and II and Then a Commodore PET 2001 in 1978 (with 8KB RAM) then the original IBM 5150 PC in 81 and later fitted with a 5161 Expansion unit and 10 MB HDD. AT 6Mhz with zero wait state RAM and Weitek with 20 Meg HD in 1985.
That news is nearly 30 years out of date. Bill Gates cobbled DOS together from Q-DOS, Xenix (the largest UNIX varient at the time) and made it resemble DR-Dos's CP/M and then got a rare non sole supplier contract with IBM for DOS.
Sim Wong Hoo did not invent the sound card, but he certainly was the most successful marketing person when he formed Creative.
Bill Gates did not invent the operating system for PC, but he certainly was the most successful marketing person when he formed Microsoft.
Apple did not invent the mp3 player, but they certainly did well with the iMac and iPod based on how they marketed their products.
