Overview of the ML-1
Under the Hood
|
Lookie what the postman delivered today... It's an ML-1! This is the rack mount version of the synthesizer, as opposed to the "tabletop" unit. It's designed to slip into a rack, so there's no case other than the basic card cage and all that. The following set of pictures is from my disassembly of the unit.
The front as received.

Flat bottom view.
The screwdriver comes out! The back screws are loosened, and the two backplane boards are pulled off revealing the inside of the card cage.
Closeup of the backplane boards. It appears that this unit could be configured for multiple uses by changing these boards, and changing the cards in the cage. There are some empty card slots too.
The naked cards, exposed. Note the four large plastic "cards" in the bottom of the cage. These are the four potted modules.
Backside of the front plate. I like how there are some blind holes in it for the rivets on the card cage, so it can be mounted flush. The pots and switches and such mount to the subchassis and merely poke through.
The cards have been removed and a drawing was made as to their locations.

The front backplane board has been removed. This connects up all 8 boards. There are some empty spots on the boards for other connectors. I wonder what options were available for this unit that would connect there? All of the controls are carefully labelled after being removed from the subchassis.
Once the controls are labelled on the board and with tags, they are removed to reduce clutter and prevent damage.
The cards and backplane boards have been removed, leaving pretty much an empty shell of a unit. Now that it is all removed, the real work can begin!
Another view of the same.
