byte) dynamic RAM on the Control module. The Emulation Ram can be map-

to any address in the Target memory map and is normally used to em-
ulate PROM or ROM which will eventually contain the Target program.
4. Interface RAM. '!he Interface RAM is a lk byte static RAM on the Control
module which is used for interface between the system and the Target.
This RAM can be accessed only by the system and is loaded with the
interface control program. '!he Interface RAM does not appear in the
Target memory map when the Target program is executed or examined, but
is shadowed in during debug.
