- Shift data in register A left one position and write to register B
- Copy data in register A to register B
- Jump (based on a few conditions) to an address encoded in the instruction
- Jump (based on a few conditions) to an address in register A
The backplane will have SIP sockets, and the risers will have right-angle SIP headers that plug into them. By expanding the buses from a 40-pin socket to a single row, it will make wiring much easier.
Here's what the backplane currently looks like:
Once the backplane is complete, it's just a matter of building the various boards one at a time. Each board will be relatively simple, making building and troubleshooting much easier than trying to build the whole thing in one shot.
