yes thats it thanks saved me drawing it.
output CPU A should be capable of driving a cmos input, as long as CPU B is a modern type, and CPU A isnt a realy weedy type. dont forget you usualy need capacitors to ground on both pins, and ofc the capacitance of the CPU B input means you might need slightly less on that node.
yes id like to know too.

Yes, the caps to ground were a exercise for the user. :-)

PS: I wouldn't use this in production. But it might work on the bench. If the OP has a board were he can try several chip of both types, CPU A and CPU B to see if they are consistant.
