ZDS/ASPIO
AUXILIARY SERIAL I/O BOARD
The ASP10 board provides one auxiliary parallel com-
munications interface and one auxiliary serial cornrnunica-
tions interface for the ZDS-I. A parallel interface is designed
for communications with the printer supplied by Zilog. &o
a printer employing the interface characteristics of the Cen-
tronics Model 306C may be used (e.g. Tally Model 1202 or
1602, Wang 200W). A serial interface, utilizing a Universal
Asynchronous, Receiver/Transmitter, is provided to enable
synchronous or asynchronous, full duplex communication
with external devices employing RS-232C interface charac-
teristics. Utility software is provided for the parallel printer
interface and diagnostic (exerciser) software is provided for
the serial interface.

CENTRONICS INTERFACE BOARD
Two specialized parallel interfaces are provided, one
dedicated t o interface with a Prolog 90 Series Prom Program-
mer and the other for a varallel vrinter interface ureviouslv
described under A S P I O . ~ U ~ ~ I ~ ~ ~ software is p o v i i e d for eich
interface eliminating the need for the user t o develop his
own utilities.
