The A1500 was a special model only ever released by Commodore in the UK, and should not be confused with the Checkmate A1500. It is actually nothing more than a rebadged A2000 which came with two (880K) internal floppy drives instead of just one and was not sold with a hard drive. Infact on many A1500's you can peel off the A1500 sticker to reveal "A2000" underneath.
