Description

The A314 project provides a Raspberry Pi expansion to the Amiga 500 through the trapdoor expansion. Much of the 'magic' is being able to transparently access chip RAM without interfering with the performance of the Amiga itself. However, the Amiga 500 is also the ONLY Amiga model to feature this peculiar expansion interface. This board will add a standard 56-pin "trapdoor" interface to the Amiga 2000 and Amiga 1000 equipped with a Rejuvenator.
