First of all, the components are aligned with pin 1 being the square pad, though you probably knew that. The front of the board for the components is the side with the "Rev A<cr>J. Grand 2001".

When you plug the board in, the chips should be facing away from you. If you have trouble with alignment for some reason, stick it back in the cart.

Other things wrong might be cold solder joints or other incorrect soldering techniques causing loose or no connections (believe me, I've seen some REALLY BAD soldering by homebrew people before :), improperly programmed EPROM, bad logic gate, etc. There's really not much that can go wrong on the board, considering how simple the design is..

Soon (I promise!) I'll have pictures and general assembly instructions on my website..

If I have the PCB facing me, with the narrow (cartridge slot) end at the
bottom, and the side that says "Rev A<cr>J. Grand 2001" facing me (and the
writing therefore on the left side), then I should just drop a 2732 into
the upper socket, with pin 1 at the upper right, and a 7404 into the
lower socket, again with pin 1 at the upper right, correct?

And then when I plug it into the Atari, the chips should be facing the
ceiling.  Is that correct?

Because if so, it ain't working. Am I missing something really obvious?
