Very Rare Repertoire PTY LTD Apple Mac Macintosh Guitar Music Keyboard

Description

Very Rare Repertoire PTY LTD Apple Mac Macintosh Guitar Music Keyboard.
I have collected, bought, restored, and sold many computers and accessories and have never seen anything like this before.  This appears to be a keyboard with musical note instead of the alphabet and numbers.  It came with a Macintosh 512k that I had purchased.  The computer didn't have any driver software for it and no software came with the keyboard.  I am not even sure if it needs driver software or not; I would image it does.  This is untested.  I am selling as-is with no returns.   The guitar keyboard has a lot of yellowing but no cracks anywhere on the case.
Please see the photos for content and physical condition.  Selling as-is with no returns.
