(And don't forget, judicious use of vias can solve a lot of problems. It should be possible to do a keyboard in two layers, the trick is working out where you need to jump a column from one side to another.)
    I cannot believe people like Lee Felsenstein used to do this with light tables and tape!

    You started with red and blue pencils on paper.
    The tape was the last step so you could make clean photo separations to send to the board house.

    Interesting. The account I read of the creation of the Sol said Lee and another guy were constantly having to readjust the tape to accommodate Bob's last minute changes or problems they found in the design, and they didn't even succeed in getting it fully right.

    1) When you are laying tracks, do you lay them just to the edge of the pads for each DIP socket? Or do you go right to the center (the hole)? I'm assuming to the edge.
    To the center. Pcbnew (KiCad PCB layout program) knows how to connect the wire )track) and the pad. If it passes the DRC without any "not connected" errors afterwards, you have done it right (at least this part).
