I thought the 628 was an 18 pin chip.  :)

You might want to look at mill-max dip IC sockets.  They make fairly 
long soldertail sockets.  the pins are 20 mils wide and 170 mils 
long.  That might work though its a hack.  mouser has them.  p789 of 
current catalog.

I'd suggest you skip the socket stuff altogether and build an ICSP 
header on your target hardware.  You could get an 18 pin socket and 
solder on the 5 wires you need for the 5 (or 10) pin ISCP socket.  
ICSP is 10X easier than prying the chip out of its socket and 
sticking it into a programmer *every* *time* you make a change.  
Also, you can just ICSP to a seperate socket.

Another approach is to get a "dip clip" and connect the appropriate 
pins to the ISCP pins on your programmer.  Then to program a chip in 
circuit, you just clip on and program away.
