There has been a hitch in arranging a stencil for the AND gates (thanks for nothing, Paypal) so I have hand-soldered the first one to test the design:

Next up, a jig to test finished AND, OR and NAND gates. I also intend to whip up a carrier board to do some speed and propagation delay tests.

Also, I have repaired the 4 faulty flip-flops from my first batch of 20. The usual problems - diodes around the wrong way, missing resistors.
