2.2 Evaluation Operation
2.2.1 Overview
The emulation configuration is for high-level debugging using a dedicated debugger running on a
development host; the evaluation configuration, for stand-alone execution of the user application
program from EPROMs.
The MODE switch switches between the two, taking effect the next time that the power is applied or the
reset switch is pressed.

2.2.2 Operation
The evaluation configuration produces real-time emulation of the user application program from
EPROMs. The two EPROM sockets, labeled EPROM.HIGH and EPROM.LOW, accept the following
types.
•
MSM27512 and compatibles
•
MSM27101 and compatibles
The emulator cannot program EPROMs. Use a commercial EPROM writer to write the two object files
generated by the dedicated assembler to separate EPROMs.
