Getting Started
INSTALLING THE ZT 8832 WITH DOS MPX
The DOS Multiprocessing Extension (MPX) software provides a
development and operating environment for one or more ZT 8832s in
a DOS application. DOS MPX allows programmers to develop
applications using a high-level language such as C without the
problems associated with placing the program in ROM.
DOS MPX includes a boot EPROM for the ZT 8832, an installable
device driver for the system master processor, and a utility for
downloading programs from the master processor to the ZT 8832.
Memory Requir
ements
The DOS MPX firmware is shipped in a 64 Kbyte EPROM. Install
the EPROM into the ZT 8832 socket labeled ROM. The 28-pin device
must be right justified in the 32-pin socket, as shown in Figure 2-2.
DOS MPX requires at least 32 Kbytes of local RAM. Installing a
32 Kbyte RAM in the socket labeled RAM LOW meets this
requirement. The 28-pin device must be right-justified in the 32-pin
socket, as shown in Figure 2-2. If more than 32 Kbytes is needed, a
second 32 Kbyte device can be added to the RAM HIGH socket, or
larger RAM devices can be used.
Cable Requir
ements
DOS MPX shares video and keyboard with the system master
processor. The only cabling required is that dictated by the application
requirements.
