My ZX80 came with a ZX81 16K RAM pack and it works fine; ISTR physical
differences aside the only real difference between the 80 and 81 was the ROM
anyway, so by the time you'd bunged a 81 ROM in your 80 you ended up with an
81! The ROM even came with a 81 keyboard, overlay or real keyboard; can't
remember which.
The Jupiter Ace had a 4K RAM pack as well as a 16K one, and if anyone has a
spare Ace (UK) or Ace 4000 (US) I'd be happy to take it off them :o)
