Data East Cassette to JAMMA Adapter

Description

The DECO Cassette System was introduced in December 1980 by Data East. It was the first arcade system that allowed arcade operators to change games and used audio micro-cassettes as the storage medium. Operator were required to purchase a generic DECO cassette cabinet, and games would come in form of a kit that would include the instuction manual, the cassette and a security dongle.

On power up, the system would load the contents of the game from the cassette into ram, which took 2-3 minutes on average, and the ram would retain the contents of the game until rebooted.

The system itself proved quite unreliable, and did not sell very well. Today there are very few of these systems still in working condition. In addition to that, many of the popular games released for the DECO system, were re-released as a standalone, ROM based game, it their own dedicated cabinet. In fact, many more of these dedicated games exist today.

This adapter aims to be compatible with the dedicated versions of the DECO system games. Many of these dedicated ROM based games share the same or very similar pinout, which was quite different from the original DECO cassette system pinout.
