Why do you talk about this?
The A600 card has 64 MB.
And 64 MB and 80 Mips is the best one could ever get for an A600.
Seeing this video now leaves me with a slightly bad wish for a version that fits over my Minimig's 68000 CPU, just like an A600.
Yes I know its not likely to be technically feasible or very worth while as they are not that many minimig's out there and a newer FPGA clone Amiga is the a better solution, but for some odd reason adding a faster FPGA CPU to my FPGA clone A600 just sounds fun :-)
Anyway keep up the good work I really enjoyed the video and when your A600 board becomes available I may just need to add an A600 to my Computer collection.
