Has anyone ever constructed a unit from the released schematics for this unit?

I know there are a few protoypes from Coleco out there.

A new Original schematic arrived today for a side port unit. I was suprised that I had actually purchased one of the unit a year ago, not knowing what it was. Turns out the Production Numbers match!!!!!

Great News and information coming. John Lundy of LundyElectronics.com was able to test and repair this unit. We are now further analysing it and its relation to the software that utilized it Coleco Graphics Processor (C.G.P.)/Project Name By Line.

Muchmore to come.

Jump in and provide your insight and feedback.
