I visited CHM in early 2018. I actually didn't go to CHM proper, but arranged with them to visit a warehouse nearby where they store a lot of stuff they don't display. I was able to see my "first personal computer" circa 1962. It was an IBM 709, the last vacuum tube computer from IBM (I thin

The US Letter size of folded Versatec paper came in a cardboard box that was really good for compartmentalizing small stuff and stacking for storage!  I used to scrounge around the waste containers for empty, used boxes. Still have many in use. Dave On 4/13/24 11:40 PM, Tony Duell via cctalk
