The first PC I built, a HeathKit H8 (ocatal keypad on the front panel), ran HDOS in 8k RAM. I was happy to upgrade to 64k RAM (cost US$800) and CP/M 2.2 with a 3-drive system of hard-sector single-side single-sector 91k 5.25" flops (disc system cost US$1200 for 273k storage).My first PC ran CP/M. I was delighted to upgrade to an IBM XT with a massive 10mb hard drive and a 360k floppy drive.
I got rid of the Cromemco S100 system and its twin 12" drives long ago but I still own some 12" flops as well as many Hollerith punch cards, a few IBM 5150 mass-storage carts (look like plastic mortar rounds), wire-plug program cards, paper-tape spools, rolls of teletype paper, a magnetic-core memory circuit, and other museum-quality crud. Not to mention Clive Sinclair's digital wristwatch kit. I was big on kits.Somewhere I still have an 8 inch floppy, and the IBM punch cards I used when in charge of an IBM mainframe in 1963...
