If ignorance is defined as a 'lack of knowledge' (Webster's), i am guilty.

Annoying people who helped me - more often than expected - is not my intention.

You mentioned that the 8088 cannot issue FDC commands. The FDC and the Z80 can pass (read and write) data via a common 8 bit wide bus.

The patch tried to execute both RESTORE and RESET within the main driver. I understand this shortcut (and the modification of 'wd_fdc') is considered 'unfaithful' and therefore incorrect.

Are there other objections, or will a complete rewrite be in order (e.g. move FDC related registers out to a RX50 controller device that interacts with the Z80)...?
