[IBM video cards and internal header connectors]
Did anyone ever USE a light pen?
Was there a commercial light pen that would connect to the IBM< CGA card?
Given that IBM seemed to use de facto standards for the connectors (the
composite heder on the CGA card being the same as the Apple ][, the
cassette connector on the 5150 being the same as the TRS-80), I wondered
if the light pen conenctor was also used elsewhere.
Howere were you supposed to route the light pen cable out of the system
unit case? There is no obvious hole for it.
Was there ever a lightpen for the PC-jr? I seem to remember a connector
for one on that machine.
