I'm opening this as a draft for now due to issues with the WK-1800 floppy drive, any help would be appreciated:

  • pressing the Disk button with the drive empty starts the drive motor, then the firmware waits forever on some status bit that is never set
  • pressing the Disk button with a disk inserted results in several 'forced abort' errors from the H8 DMA controller
  • wk1800 firmware seems to rely on different TS bit behavior from the HD63266 compared to a standard uPD765, but I have not checked this against other machines that use the same FDC (e.g. those Brother word processors)

I'm going to un-draft this now with the floppy support removed since I don't have the time to take a deeper look at the issues with it right now. Everything else is working.
