If it doesn't contain a perfect SID sound and allow use of a Zipstick it ain't no C64 let alone worth $600.
My friend is loaded, he loves C64 and I sorted out 3Gb of 8bit Commodore games and emulators for him to play......even he wouldn't buy one for $600 I wouldn't buy one for sure. So a few thickos will be buying one....then nothing.....dead end.
What they should have done is resurrect the C64 DTV for $15-20 in massive quantities AND wired one of those FPGA boards to the C64x case & keyboard for $99.
If people want a cheap shit PC they can buy one for $250 too, total = $350. half price of C64x
Greed is ugly.
