I'm looking for information on an old Maxi keyboard I picked up for free recently.
The model I have is a 2189001-00-411 which doesn't match the number that I see referenced for Maxi-Switch ME 101s (218903).
I've tried out the keys and enjoyed their feel so I'm looking to get this hooked up, but before I do, I wanted to read up on the dip switches and any documentation, but I can't find any references to this series.
Does anyone know anything about these keyboards or can point me in the right direction? I've included photos of the exterior and the board inside, which is a daughter board connected by ribbon cable rather than controllers built into the board.
I've included images of the internals and back and front.
