Monochrome Monitors


Black and White


Working with several Midway Gun Fight machines and Space Invaders and Space Encounters and Clowns and Atari LeMans and Kee Games Sprint 2 has me learning something about monochrome (black and white) monitors.

I see mostly Motorola XM700 monitors. I also encountered the Midway Manufactured 161 monitor and several variants.

Making the Connection



The Midway 161 monitor has 5 pins hot ground and neutral for AC power and Video signal and ground. This series features the smaller pins in the 9 pin black connector.

The Motorola XM700 (marked XM701 or XM 702 in my collection) has the same 5 pins, but in a more standard size pin with a 12 pin white Molex.

Classy Chassis


The chassis are completely different. The Midway is a much larger system with power controlling daughtercards and too many capacitors to mention. The XM700 looks like an electronics project with dozens of pins on each side, but it is the more compact and simple design.
