I'm hoping to build a system to run ETOS, a PDP-8 multiuser system. One of the requirements is a system clock for time slicing and stamping. I'm looking for either an M882 (line frequency) or M8830 (crystal controlled) clock card.

This may be a good reason to do the ETOS board as FPGA vs origional logic. It would be easy to add the clock logic to it.
