Yeah, haven't seen much about it but it looks and seems really cool! Buy why oh WHY doesn't the fscking landing page have the tech specs? I spent way too long trying to navigate their maze of documentation without finding a basic listing of the raw specs (and whether or not it's FPGA based, since that sometimes matters for retro computing). No dice.
Checked for a Wikipedia entry, but found only the "real" Commodore 65 that the Mega65 is based on, and it does not seem to have been 40X faster than a C64.
Finally found a German retailer's page, with some actual specs, yay [1]! So it is FPGA-based, in fact there's three of them if I understand correctly. Cool.
