Remove the "keyboard"-CIA, and you have no interrupt: cursor does not blink. Remove the "drive"-CIA and you have no normal screen as this CIA steers two lines of the VIC. Presume the CIA of the MAX is the "drive"-CIA and the rest of the hardware (addresses and wiring) is the same, you only have to "move" the interrupt by replacing the addresses of the used timer by the ones of the "drive"-CIA.
