I don't find this off-topic at all. The logic seems to include a new
68000 CPU core, which is relevant for QL hardware.

The core seems to be a cycle-accurate 68000 CPU, which could allow to
implement a GoldCard on FPGA without repeating the difficult software
timing adjustments for QL network and Microdrives.

The 68000 CPU core used inside the Q68 is not cycle-accurate. For speed
reasons this can be nice, like the single-cycle multiplier. But whenever
there are timing loops, a cycle-accurate implementation helps a lot.

All the best
Peter
