[hpsdr] Appropriate Altera part choices

[Alex]

So an argument could be made that most plugin cards should use the MAX II, and the more complex plugin cards (OZY,  SASQUATCH, etc.) should consider using the Cyclone II.

Has JANUS (or MERCURY) completed the ATLAS bus interface using the MAX II? If so we should consider using it for GIBRALTAR and other cards. It will help with debugging and development if we have common design elements. 

Plus PROTO (the prototyping board) could be designed reusing the same MAX II element and vhdl interface code.

Janus will be using an Altera EPM240TC5 100 pin TQFP for the CPLD rather 
than a Cyclone II.  Lots cheaper, and instant on, better fit for the 
particular application.
