I'm working with an old data sample (ca. 1979) to a piece of
equipment that I do not have access to. I've identified some bits
and pieces of code and am trying to identify the processor.
Here's what I know. The processor is big-endian and appears to be
byte-addressable. The opcode for CALL appears to be D3 xx xx, where
xxxx is the address of the destination. 2C appears to be load
immediate instruction and is also 3 bytes long.
The code doesn't look tight enough to be a p-code implementation of
any sort.
Does this ring any bells to anyone?
