I ordered my components for part one of Mary Ann... the color bar test.  I already have an additional Atmega 162 - so no need to order that.  But I needed the following to complete my color bar test.

AD724 and a 3.579545MHz clock for the video timing

I noticed there is an AD725, and I was tempted to order this newer? model, but then I noticed it requires a ~14mhz clock and I'm trying to keep this whole breadboard project under 8mhz.  The AD724 is capable of applying a 4x multiplier to the 3.58 MHz clock.

Unfortunately the AD724 only came as a surface mount... and I've destroyed too many chips trying to solder the surface mount connectors to a DIP adapter board - I need to practice.  For now though I ponied up some extra cash and had proto-advantage do it for me.  It's not cheap, but they'll order it directly from digikey, solder it to an adapter board, and send the finished product.  I've used them many times and the quality has always been outstanding:

I'm SUPER excited - as soon as they arrive I'll bread board it up, finish up the ASM code and give it a shot.  I'll post back with the results!
