JAMMA Monitor Tester

Regular price $44.99 CAD
Regular price Sale price $44.99 CAD
Sale Sold out
This is a small battery (CR2032) video tester / signal generator made specifically for testing arcade monitors in JAMMA cabinets. It is the size of a typical JAMMA fingerboard and can be easily carried around in your pocket for on the go testing. With an additional cabinet adapter (see my eBay store), a number of non JAMMA cabinet monitors can be tested as well.

The tester supports the common 15kHz standard resolution, as well as the 24kHz medium resolution and 31kHz high resolution arcade modes, with JAMMA standard negative composite sync. The tester can be operated from the control panel (Player 1 Buttons 1 and 2) and can be powered by either the cabinet's power supply or the CR2032 battery.
