52e33e861c Starts to introduce the QL as a second source for 68000 testing.
It's advantageous over the ST in that a commented disassembly of the ROM is available.

Thomas Harte
388d808536 Switches to providing UDS and LDS implicitly via address.
Also makes sure that the difference between a non-data cycle that starts without the address strobe active and one that starts with it active can be discerned.
