And there it is

I haven't put together all the patterns for it yet, I have some ideas. The area around the chip is wretched because of the home-etched double-sided board; there's no feed-through so I had to disassemble an IC socket and solder the pins from both sides, which is really pretty difficult. I should buy some wire-wrap sockets to facilitate soldering on both sides. Either that or do all the chip stuff on the bottom and go to the other side with vias.
