Implement Expansion Board serial ring and test ports #768

Open gardners opened 8 months ago

Is your feature request related to a problem? Please describe. The MEGA65 Expansion board I am designing has user port and tape port and C1565 port that are all connected to some degree using a ring of serial shift buffers. We need to implement this ring, and test it with the board.

Describe the solution you'd like I implement the ring, test it under simulation and with real hardware, to confirm it works.

Describe alternatives you've considered Sleeping in
