An interesting little project by Norwegian developer Stian Søreng, the APECAT - short for "Amiga Processor Expansion Card for Application Transfer" - aims to enable you to upload data directly to your Amiga's memory.
The APECAT - a successor of the "68k Sandwich" (see "Sources" below) - is quite a simple circuit board, using an ATmega128 controller, that sits between the Amiga 500's mainboard and the MC68000 CPU. Being able to use a PC computer and this board to "inject" software directly to the Amiga's RAM would hugely simplify a software developer's work, and also has a lot of potential for retro gamers.
BUT! It doesn't work yet. So far things look promising, but there are still a few issues to iron out - so Stian Søreng asks for YOUR help!
If you're an Amiga hardware / assembler guru maybe you can contribute?
