[hpsdr] ATX connector on Atlas bus

[Phil Harman]

Second take on the ATX connector.

The boards that we attach to the Atlas bus are in many cases going to be 
prototypes and development boards.  There is the inevitable chance that 
there will be circuit and operator errors.  With a full blown ATX power 
supply connected to the bus - that can provide may 10's of amps - such 
errors can be 'interesting' to say the least.  ATX power supplies are 
intended to power production designs that are not subject to tinkering. If 
we use a small Molex header then connecting up regulated and current limited
power supplies during the testing and development phases is very simple.

Since I don't see a high power PA being on of the six boards we don't need 
10's of amps anyway.  I'm not suggesting that we don't use ATX power 
supplies for a final and proven design - just not during the development 
phases.

I still support the case for a simple, small, Molex connector on the Atlas 
bus.
