[GPS_Standard] a parts setback

I really appreciate the Digi-Key BOM.  My head starts to swim
when I get into the Digi-Key website.

One complaint:

The LTC1485 on the sample BOM turns out to be a surface mount part.
I'll either have to make some kind of adapter under my microscope
or go back to Digi-Key for the 8-DIP part.  I should have looked closer
at the list.

I have most of the system-level parts gathered:

Resolution-T GPS,
GPS antenna,
RS-232 level converter,
10811 oscillator.

I am torn between rolling my own power supply or ripping the one out of the
nasty 5328A counter from whence came the OXO.

When I get the board populated I plan to do a bench test using bench 
supplies
and see if it all is going to work.  I may come  back to the list for
help with a GPS timing amp if it turns out I need one.
