Description
The DECO Cassette System was introduced in December 1980 by Data East. Because the system proved to be quite unreliable, and did not sell very well, many of the games released for it, were ported to its own, much more reliable, ROM based dedicated hardware. Reliability continued to play a role in ongoing maintenance, and as a result, there are far more dedicated game boards out there today than there are DECO Cassette Systems.
A few of these dedicated ROM based games share a similar pinout, and others, especially the very early ones, are unique. This adapter aims to be compatible with the dedicated versions of the DECO system games that have a common pinout.
Note: This adapter was previously called “Data East Cassette / Dedicated”, which was changed to “Data East Dedicated” to avoid confusion with the actual DECO Cassette System adapter. Pictures below will be updated to reflect that.
