I am considering purchasing a Data East Time Machine near me, but Have just discovered that it is missing the Chime Unit assembly and Knocker.

How hard are the chime units for these games to find, and is it possible to replace them with a similar chime unit?

If anybody happens to have a spare Time Machine Chime Unit assembly (part number 500-5123-00) lying around they want to sell, please let me know.

Alternatively if you can point me in the right direction to find a an alternate chime assembelly replacement that will that easily install into the game, I would be grateful.
