Getting Started
Configuring the ZT 8809A for STD ROM
The STD ROM development system is available as an option to the
ZT 8809A for software development. If STD ROM is ordered along
with the ZT 8809A, the board is preconfigured and tested at the
factory prior to shipment. If the system has been altered or the
ZT 8809A rejumpered and the system does not function properly,
refer to the following instructions and to Figure 2-1 for configuring
your ZT 8809A.
STD ROM Memory Requirements
The STD ROM debug monitor is shipped in a 64 Kbyte EPROM.
Install this EPROM into the 32-pin socket at location 5D1, right
justified, with the board oriented component side up, goldfingers to
the left (see Figure 2-1).
STD ROM requires 2 Kbytes of memory, from address 0 through
7FFh, for program use. The 32 Kbyte static RAM shipped with the
STD ROM system should be sufficient for both debug and application
program memory. Install this RAM into socket location 7D1, right
justified.
If more application program RAM memory is required, another
32 Kbyte static RAM may be installed similarly into socket 9D1.
