A better solution might be to use a small chip-based computer that has
both digital I/O lines and a serial com port...
With such a configuration it would be possible to interface the power
glove (or any alternative input device) to the macintosh serial
port...
i.e.
alternative I/O device ->
chip computer's digital I/O port ->
chip computer'S Serial port -> macintosh computer serial port
the Intel 8052AH-BASIC chip computer is perfect for this task...
... programmable in BASIC, the device can be set up to act
as an interface between custom I/O designs and a Macintosh.
