I'm thinking today about what it would take to fork Mu for the Raspberry Pi. It uses ARM processors, a 64-bit instruction since the Pi 3 which was released in 2015. The 64-bit ISA looks quite nice, but it's incompatible with the Pi 1 and Pi 2. Contrast x86, where 64-bit is quite compatible with 32-bit, but grotesque as a result, with bits for a register scattered across multiple bytes. So I might make the opposite choice to x86 and support just the 64-bit ISA. Thoughts?

@akkartik 64-bit ARM quite possibly more future proof than the existing x86_64 fork and it targets cheaper / widely available hardware. I like this idea :)
