Hi,
does anybody have good documentation/demo source about the RIOT?
I am especially interested in the timer function.

Note: there is a "quirk" with the RIOT timer on the 7800. Because the RIOT clock line is slaved to the 6502, which is controlled by MARIA, it gets impacted by the "downshift" the CPU makes when it accesses the TIA and RIOT.
