Ok, appears as though the FDC Busy flag is set, which it as I understand it, shouldn't be during a seek or recalibrate. Having the busy flag in the main status register reset at the beginning of a seek/recalibrate gets elwro800 running, and booting CP/J. Bondwell 12/14 still works, and I tested the PCW, CPC and X68000 drivers which also still appear to work. Reply if you know of any drivers broken by this change.
