Space Duel to Major Havoc Conversion Files

I scanned a few original Atari documents related to converting Space Duel, Black Widow, Gravitor, to a Major Havoc. The scans were done at 1200 dpi in B&W. The control panel wiring diagram was really spotty and hard to read so I cleaned it up.

This is the schematic, parts layout, and parts list for the SD-to-MH conversion board. This board is not the same as the Tempest version...
