MTAB 68K-2
The MTAB 68K-2 Microprocessor Trainer is a powerful
and cost-effective complete single -board microprocessor based on the
Motorola 68000. CPU supported by the popular peripheral chips from
Motorola. The powerful system monitor includes one line assembler fro
Pneumonic entry, disassembler, and Centronics printer interface driver
in addition to the user friendly set of debug monitor commands. ABORT
facility permits graceful recovery, preserving the complete user context,
from "STUCK" Careful bus attribution design permits the access
of all on-board resources by an off-board master making it easy to
expand ESA 68K-2 into a multi-master configuration. Thus MTAB 68K-2
is a valuable id for teaching, software and hardware development in
academic institutions. research institutions and R&D labs. |
