I need advice on how to proceed with a machine that does not seem to read the reel opto's. I get a 42 error after the first spin after which the machine needs to be reset. In switch test mode I also only get a reading on the first reel.
Swapping out the reel readers confirms that they are all ok but only in position 1.
Power supply test points give expected voltages.
I've traced the wires from the reel readers through the reel control board up to the IO board. All connections seem to be fine. What bothers me is that in switch test mode all the control bit lines remain low so only the first reader board is selected.
Is there something obvious I'm not looking at? Are there schematics available for the CPU and IO boards?
