I don't suppose anyone can help, but I'll ask anyway.
I have an IBM 836 Keypunch, which is similar to an
026 keypunch but has a patch panel in a pedestal to
the left of the users knees.
It also has three 40 pin connectors on the back panel.
Does anyone know the capabilities of these? Where
can I get matching plugs? The logic levels are presumably
suitable for the relay logic within, but any idea what
actual voltages and amperages are?
