I had the same moment of confusion that Bill had. Perhaps a short note
explaining the substitution would not be out of order.
I gave myself a scare on the front panel board. I carefully soldered
all 40 pins of the socket for U1. Then I carefully looked them over
under a magnifying glass to make sure I didn't have any solder bridges
or cold joints. About half way through the inspection I realized I had
installed the socket on the bottom side of the board. Of course,
that's where it's supposed to be, but for about 20 seconds I had a real
panic attack...
