[atari7800] CTRL register RM bits

Thanks, Dan.

And here's another question, this time about the read bits in the CTRL
byte.

Here's the Maria doc:

      RM1, RM0           -    Read Mode.
                              0 => 160x2, or 160x4
                              1 => Not used.
                              2 => 320B or 320D.
                              3 => 320A or 320C.

Has anyone done testing to see what happens if you set read mode to 1?
Anything interesting?

Thanks,

-Bob

I think the 6/9 already includes the 3 cycle character map access. A
single
graphics byte takes 3 cycles, an indirect 1 byte (1 character map, 1
graphics data) takes 6 cycles, and an indirect 2 byte (1 character map,
2
graphics data) takes 9 cycles.
