Halting both VIC and CPU would be interesting, but being able to access 
memory while the C64 is running was the main aim & I don't think there 
is a way to stop VIC externally.

Having the cartridge strobe the control signals at the right time and 
then handshake to an Amiga to perform the next transfer on an interrupt 
was the goal.
