MIDI Maze ?-??-89

This is a rare example of one of the later XE prototype board designs.  Unlike the earlier daughter card attached to a main board via a ribbon cable mess, this board combines the two into one nice large T shaped design.  While this prototype seems complete, a later version with a copyright of 1991 has recently surfaced.

The game identifies itself as Version 1.00, but seems complete and bug free (which is unusual for the first version of any game).  Interestingly the later prototype dated 1991 also identifies itself as being Version 1.00.
