[hpsdr] ATX connector on Atlas bus

[Christopher T. Day]

One of my problems with this idea is that the Atlas board then becomes
strictly a development board; the design _must_ be redone for any
end-product that might come out of this project. It seems as though the
board would have a much larger market if it could be used as-is for
end-user products as well. That's also why I'd like it if the board
didn't _require_ a heavy and relatively expensive computer case, just
_allowed_ it for the much smaller developer customer group, and why the
size shouldn't get too big..

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.
