[Ads-l] software "patch"

Thanks Ben. The1954 definition of patch (noun) emphasizes the
rerouting of control into a routine and out of the routine. This is
analogous to changing the incoming and outgoing lines of an electronic
component. That is the task accomplished by a patchboard or patch
panel. OED has entries for patchboard and patch panel. These seem to
be the closest precursors in the domain of electronics.

The 1952 citation mentions "removable patch panels of the type used in
the IBM punched-card machines". Interesting. I am not sure what it
means.

[Begin OED excerpt]
patchboard noun
= patch panel n.2

1949 Receptacle patch-board for 500 element connections and 25 main busses.
Mathematical Tables & Other Aids to Computation vol. 3 512

[Begin OED excerpt]
patch panel noun2
A panel in a computer or other device with a number of electrical
sockets that may be connected in different ways; a device in which
incoming and outgoing lines may be interconnected; = patchboard n.

1952 It should..be possible to provide so-called removable patch
panels of the type used in the IBM punched-card machines.
