I don't know the final device's arch but AFAIR (or tend to believe) the first one was done with FPGA and that included the VIC (?) And Jeri can possibly be still reached to ask (?) in case some things are not clear. > Another interesting part would be to emulate TED in TTL... Like they did with the ZX Spectrum ULA in the Harlekin... Might need a lot of TTLs since TED can do a lot more than the ULA. :) Not really practical, except for fun alone :-) -- SD!
