Just arived in the mail today…
Note: “SixtyClone” is a C64 replica PCB, compare
The first one shown is “Pulse64 – Alien Eliminator”, https://www.uni64.com/en/p/pulse64-alien-eliminator
the second one “ATX64” by Uni64, https://www.uni64.com/p/atx64
Yeah… I kind of know it. If you want to see my SixtyClone, then search Black Bessy on youtube.
