Don't get excited, it's taken me a day to get as far as working out how the lamp lines are selected, and I still haven't worked out where the lamp information is actually being written.
It's a weird system - rather than writing to the transistors directly like MPU4, there's a dedicated RAM block used, with the accesses strictly controlled by programmable timers.
