John has it correct.
It is facinating reading this text. A modern quantum physics book
presents the theory as cold hard fact... but back in 1930 when it was
brand new Heisenberg was presenting it in an almost appoligetic and not
quite sure manner.

I will give you all a couple of clues..
The equation garbled as it may be is the more complex version of E = M*C^2
Next go see who received the Nobel Prize for Physics in 1936.

Not sure I want to hand-make that many precision boards.
If I were to product-ize it, I'd go with a larger single-sided board.
You still want the solder mask, I think, although it's hard to squeeze
it between the IC pins.

They're X5R's, rated at 10%.
That board is going about 700Hz+, so they're 5% off, but I've seen
them up to 20% off when measuring them with my multimeter, not

There are two oscillator configurations, so the schematic has two
places for caps for each oscillator. You only populate one each.

I'd have preferred tsops, but I can do trace-between-pads with SOJ,
and I was kinda limited given the part I needed (5v SRAM).
