Tech: Discs of Tron Power Supply

Archived from groups: rec.games.video.arcade.collecting (More info?)

Does anyone know much about the differences between the MCR II and MCR III
systems? I picked up a DOT upright with a corroded power board. The board
appears to be the same part number as the known working power board in my
Satan's Hollow. Is there any reason this board shouldn't be used in a DOT?
Also, since the board appears to be the same, what issues would I have in
using the MCRII switching power supply kit (arcadeshop style) which
essentially replaces this board?

I've tried doing some internet searches but haven't found many answers. The
DOT manual is very vague about the power supply/board other than the
schematic which is mostly Greek to me.
