ROM dump looks correct after checking disassembled code.

Looks like all Keyboard controllers are connected
in the same way (need to check IRQ lines) for all Compass models
and have the same fimware functionalty and Keyboard keys lookup tables

Looks like 1137 firmware have minor differences. Not 100% proofs yet.
Different binary probably is because source code was compiled
with different (more modern) version of 8041 assembler.
