[comp.sys.apple] Connecting Apple IIs via the Joystick Port

jeffn@nuchat.UUCP (Jeff Noxon) (01/09/90)

I need to be able to connect three computers (A IIe and two II+'s) via the
internal joystick connector J21.  Annunciator 0 (an0) and Switch 1
(solid-apple, sw1) must be connected so that any computer can read (via sw1)
the state of the other two machines an0.  I don't care if a computer can read
it's own annunciator or not.

Example:  If computer 1 turns on it's Annunciator 0 the other two
          computers can tell that by reading the state of sw1.

Only one computer will have its Annunciator turned on at a time.

I really appreciate any help I can get!  Please email replies.
