Another update for everyone interested in the composite boards…

I ordered 50 PCBs for the A type yesterday, so should be about 2 weeks on those.
After going over some prices I’ve decided I’m going to offer these at $25 ea assembled.

I’ll be ordering the B boards soon.  After putting an oscilloscope to the board I can see
the signal isn’t exactly where I want it, so I have a little adjustment to make there.
Shouldn’t require a board redesign though, probably just a change in a couple of resistor values.
I believe the difference is due to slight differences power supply voltages in the two
motherboard types.

A question for people wanting a B board.  Is the switch for B&W mode something people
will want?  It adds about $8 to the overall cost.  I’m thinking about just offering this one as color
only, though the connections will be on the board, so you could run your own switch.
Some shielding will also be recommended for the B board if using B&W mode.
