Hello,

This is a tested and working project.

This A500 2MB Trapdoor memory Expansion Gary Adapter is an Easy DIY project, all components are through hole, marked on the PCB, Easy to solder, Easy to make ;)

This adapter is designed for use with 5719 (GARY) on Amiga 500 Rev.5 and Rev.6 boards for 2MB Trapdoor RAM Expansion.

This 5719 Gary adapter works with 2 Mega Bytes Amiga 500 trapdoor memory expansion card.

This adapter does not provide memory increase by itself, it must be connected to the 2MB memory card in the trapdoor port !
