So - I've been looking for a list, or chart, that would highlight some common characteristics for LED-ing various boardsets and manufacturers. So something along the lines as what I've highlighted below. I haven't been able to find anything for this information (or other basic board/repair information). Any ideas?
Manufacturer - Board Name - Years - Ghosting - Strobing - Flicker - Other Comments
Williams - System 11A - 1986-88 - Yes (Non-ghost bulb) - No - No - Flasher lights require warming board modification
Bally - MPU 35 - 1979-86 - No - No - No - Requires modification (lamp socket resistor, resistors in line with connector, or new board)
