I think that nothing can beat FPGAs... They are faster, cheaper, programmable and, most of all, available...
Look at the Replay: it already is what most other projects aim to be.
What if there was a plug in option for Agnus, has an FPGA to "Replace" the motherboard one (as long as it is SOCKETED), and associated RAM on the add on board to bring CHIP ram up to 8MB ?
Plug it in to an A500, and have it use the extra Ram, and an A500 will have 8MB of ram.. Food for thought.
Now if I only knew VHDL, and had Kick ass PCB development skills. Winnah !!!!!!!!!!.
