[time-nuts] FEI-5680A holes in the case

I avoided the problem of drilling holes by simply routing the added
cables out the back between the cover flange and base. For the RF output
I used a short length of the tiniest audio screened cable I could find;
for the RS232 I used flat ribbon cable of the smallest dimensions
available.

There's a bit of discussion in the archives about the need for a heat 
sink, and also about the whether it's necessary to anneal the case in a 
400C Hydrogen reducing oven after the SMA modification.  (Although I do 
have access to one, it is over the threshold for things I'm willing to
do.)
