-
- 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.
