I just wanted to shrink the SuperPET. I never thought of making a universal 6809 card for any other 6502 based systems. I do not know these systems good enough to do so.

Up to now, I wrote just a few lines of Verilog to create Q and E from a clock source, so there's still plenty of work to be done.
