I received my board on Friday and assembled it today. Thanks to all who have
helped realize this project, particularly Ruud, Jim, and Al.
The holes for the 40-pin socket appeared to be a bit smaller than the others.
I could not get the 40-pin socket included with the kit to fit in these
holes easily. I enlarged the holes slightly and then a socket with
machine-tooled pins just fit.
Soldering the headers directly below the socket worked for me as you described
but I think some people with less experience soldering will find it
challenging. If there is a future revision of this board, putting parallel
rows of pins just for the headers would make it a little easier.
I haven't yet hooked up /SEL to the 1541. I put a 10K pull-up resistor under
the board to keep it from crashing the bus until I do. It would be nice if
some holes could be added for this resistor but that's not a big deal. My
1541 works normally with the board inserted but this is the extent that I have
tested it so far.
I need to hook up an IDE drive to do further testing. I also need to build an
adapter so I can replace the 24-pin ROM with a 28-pin EPROM. I might also use
a 1541-II for testing to avoid making the adapter but its 6502 isn't socketed
so it is a similar amount of work.
Here are some photos of my assembled board:
