Before my time so to speak, but it's a program plugboard for some
accounting machine, perhaps something like the 604 or 607 electronic
calculators, or mayhaps the CPC (card-programmed-calculator).
Perhaps someone will recognise exactly which machine.
I don't know of any asbestos on IBM plug-board wires. Later plug-board
wires were typical plastic insulation, however earlier ones were
fabric-over-plastic insulation. It's just a woven fabric. Asbestos
fibres wouldn't stand up to the flexing.
