Its interesting that both processors are 6502s:
If a 6502 was chosen for graphics side/backwards compatibility and a 6809 as app processor both could perhaps be (essentially*) 1Mhz, saving on memory cost with slower memory whilst having an app processor equal or more in processing power to a 2Mhz 6502..
*either use the oric trick for lopsided vdu/6502 bandwidth in higher res/colour modes or use a textonly 80column mode or some other method.
