No, the PPG chips are soldered in, there is not enough space for sockets
(repairing them is NOT fun)..

oddly enough, look at the 2.3 proz board ;-

see the white strips?
These have capacitors and run between the 5v and 0v rail, and supply power
to the row of chips!
superb idea!!!

Ive seen the, they're expensive...
Its easier to start with a GOOD PCB layout, and cheaper..
