[Coco] Help Needed

[Dennis Bathory-Kitsz]

Hi John,

That's a parallel interface board. It was called the CoCoPort.

The 40-pin connector is an extension of the Color Computer's bus.

The 20-pin connector is for outside-world connections.

The original documentation included parallel printer interface 
directions, voice output schematics, etc.

Not sure if the original documentation has been scanned and posted or 
not, but the original articles were in The Color Computer Magazine.

Dennis
