8301, 8302, 8049 registers...

Postby Dave » Fri May 11, 2018 8:43 pm

Does anyone have any info on the registers of the QL ULA set?

For the 8301, I'm interested in ALL the registers, particularly those involved with video generation timing.

For the 8302, I'm particularly interested in the registers for serial.

For the 8049, I'm interested in the way it passes keyboard input to the 8302 and back to the system IO area.

If anyone has this knowledge and would like to write a Nasta-esque treatise on the detailed mechanism and a few gotchas, I and many others would be supremely grateful.
