ISO Pascal for the BBC Micro uses 2 16KB ROMs and runs on 32KB of RAM. These ROMs include a runtime, an editor (4KB with regex search), and a compiler.

  Yeah, but using ROMs is cheating, kind of. Also ISO Pascal wasn't that useful without extensions, which is what the famous Brian Kerningham rant was about, while ignoring that already back then C had quite a few extensions outside UNIX.

    Yeah, but using ROMs is cheating, kind of. How, exactly?
    • pjmlp 2y ago
      Because it isn't taking RAM for its own use.
      • kjs3 2y ago
        Nonsensical answer. I can load my pascal from a floppy into RAM, or I can run from ROM the same way. What does 'own use' even mean here.
        • pjmlp 2y ago
          Execute from ROM was a thing.

    Actually, this was the first Pascal faithful to the standard that ran on a diskless machine. It was really quite a feat.
