No, it's based on the AMD Xilinx Artix-7 FPGA.

Jeri Ellsworth's was actually an ASIC.

She made a "C-One" which was FPGA based, but this one is different, the C64Ultimate uses Gideon Zweijtzer's design in the AMD Xilinx.

Ah - but Jeri is still in the team. That makes me happy: https://www.commodore.net/team/

Having Amiga legend Dave Haynie on the team also helps inspire confidence.

that's quite the team. Ellsworth, Charpentier, Herd, Tramiel, etc. (i didn't recognize all the other names)

I was scrolling through that list and did at a double take at... Thomas Middleditch? The actor from Silicon Valley?

Oh, no, his start up running skills left much to be desired.

I suppose hijinks will inevitably ensue!

WTF

LOL, Leonard Tramiel - Chief Tramiel Officer
