There was a proper 64K version (called the Dragon 64, unsurprisingly): https://en.wikipedia.org/wiki/Dragon_32/64#Dragon_32_vs._Dragon_64 https://en.wikipedia.o

  Yes, the serial port could be added to the 32 as well, the rest was just software (some minor patches to the ROM). Not all Dragon 32's shipped with the 64K chips, and opening one up in the store wasn't an option so a little software test was useful. We figured all this out long before the Dragon 64 was released, and a friend of mine figured out how to move the basic interpreter to RAM and relocate it. Good times.
