Monitor 1.1 Upgrade
Towards the end of its support for the
system, Exidy released an upgrade to the built-in internal
Monitor program. This upgrade (v1.1) fixed several bugs
and added a few commands. The most important of these bug
fixes is to the cassette and serial I/O routes which makes
saving/loading from tapes more reliable. This upgraded
Monitor program was never put into production (except possibly
in Australia), but the code was released so users could upgrade
their own systems.
Interestingly, one bug present in version 1.0 was specifically not fixed. Fixing this bug, which caused a vertical tab instead of a horizontal tab when the tab key was used with lower case letters, would have broken the Word Processor Pac which was coded to take this bug into account. Since Exidy never manufactured v1.1 ROMs,
users must burn the file onto a pair of 2716 5v EPROMs.
These EPROMs replace the two Monitor chips on the motherboard
which are conveniently socketed for easy removal. You may
also have change a jumper to change the voltage going to the
EPROMs from 3v to 5v.
