Model 21 Engine board pic posted

I've posted a photo of the Model 21 prototype - the Milton 2 - in the Miscellaneous folder in this yahoogroup. What you're looking at, while not yet complete, is operationally equivalent to the Milton 1 engine board. Actually there are a few added features over the it's predecessor...and a ten of the componentry and cost and in a third of the real estate. You gotta love microprocessors. Sorry for the quality of the photo , but it gives you the 'big picture' pretty clearly. Note that stage three is lit (although the light blew out in this exposure). - P
