[Coco] Powering CoCo with 12V DC only (was Monitor Choice)

[Steve Pedersen]

Hi folks right now I'm looking at various buck and boost converters for 12
volts.
I'm also looking at the technical reference manuals looking for places to
tap in the power leads from the buck and boost converter I'll get this
figured out pretty quick I hope.
