On the Master Compact Welcome disk, the pointer gravitated to the top-right corner and stayed there. SD card joystick interface wouldn't work.
Using a test program on this thread viewtopic.php?t=11671 I saw random inputs from CB1 and CB2 when nothing was plugged in.
I was unable to work out how to do any further diagnostics, but solved the problem by replacing IC7 with a new 6522.
