Willams Sound Board ROM Strapping

Early (narrow) pinball / Defender sound boards can be strapped for 6341 (512x8), 6381 (1kx8) or 2716 (2kx8).
Later (square) sound boards can also be strapped for 2532 (2kx8). By adding jumpers to undocumented locations, 2732 is also possible.

Rally-X to JAMMA Adapter

$45.00

This adapter allows you to play Rally-X (and New Rally-X) in a JAMMA cabinet.

Burgertime / Bump 'n' Jump to JAMMA Adapter

$65.00

This adapter is jumper-selectable to play Burgertime or Bump 'n' Jump (and some other Data East / DECO games) in a JAMMA cabinet. The video board edge connector is attached with a ribbon cable.

Several DECO games use similar pinouts but there are difference in power wiring, so a jumper selects whether -5V (Burgertime) or Ground (Bump 'n' Jump) goes to pin 3 on the main connector. Other games may require different connections to this pin which may be hard-wired.

Nintendo Classic 2-1 Switcher

$100.00

This kit allows you to play 2 Nintendo games in the same cabinet and switch between them by pressing P1 Start + P2 Start + P1 Jump/Fire. An edge-connector harness is required, so an additional adapter is required if your cabinet has a 4-board style harness with the myriad of 0.1" connectors. Additionally both boards require "rainbow cables" to supply power from the CPU board to the video board.

Power, audio, and video signals are relay-switched, and all inputs are buffered, so there's no interaction or loading between boards.

Price: $100.00
