Description
The AUX I/O port is a 34-pin connector at J2 which incorporates the
parallel printer, speaker and keyboard ports, two optically isolated inter-
rupts, and the AT battery connection. An alphanumeric display, matrix
keypad, or floppy drive also interface through this port. These features
are easily accessed through the use of the breakout board or through the
construction of a breakout cable. See the product-specific appendix for the
AUX I/O connector pinout.

Breakout board (BOB)
The breakout board (BOB) is designed for use with all 6000 Series PC
Microcontrollers. Keyboard, printer, speaker, optically isolated interrupt
and reset, and an optional AT battery, are connected from the breakout
board to the PC Microcontroller through the 34-pin AUX I/O header. The
AUX I/O header provides a convenient and quick method of disconnecting
these external devices from the PC Microcontroller during maintenance.
Note The AUX I/O port supports either a printer, an MPB-16PC opto-rack, a
floppy drive, or can interface to a keypad and alphanumeric display, but
not to all at the same time.
