so spec wise if by some miracle clone-a got released how it specs wise compare to like fpga arcade and Natami MX boards?
AFAIK the focus with Clone-A is to *clone* an Amiga 500; meaning aiming for absolute perfect reverse engineered chipset for *100%* SW compatibility. The focus with Natami OTOH is to reimplement and *improve* the chipset, which inevitably will mean breaking a certain amount of compatibility. So spec-wise the Clone-A *will be* an Amiga 500 (no ethernet, usb, pci, 256MB chipmem or whatever), while Natami will be something else. Different purposes, different goals.
