FPGA Arcade is an interesting device and I've discussed it and read about it elsewhere. There are some really good features, along with 8MB chip RAM but it wont be a replacement for my A1200 060@80Mhz just yet.
Possibly with the 060 daughter board it may come close.
I've had my A1200 recapped so possibly it will last a little longer, one day it may die and FPGA or something similar would replace it.
So will keep watching for now :-)
