Now I'm thinking about the creative misuse of (non-existing) technology.

From the numbering scheme, the "4" in "RP2040" is log2(ram/16K). If we wanted to emulate a Lisa, we'd need 1MB of RAM, which would mean, at least, an RP2060 chip (log2(1024/16) = 6) or, more comfortably, an RP4x70 or RP2x80). Those parts, unfortunately, don't exist yet. Maybe they get inspired with their IPO and start making those parts.
