The first computer I ever worked on had 8KB of core memory. It was an old Digital Equipment Corporation pdp-8/e. I loved that machine and its open face tale drives and teletype with paper tape punch and reader and card reader.

Oh, I see what you mean by

Is that… 32 bytes of memory?

No, each wire that goes through the rope, weaving through or around each of the ferrite rings, represents one or multiple bytes.

Looks like there are 16 wires for each core in this module?
