Additive Programmers 3

The DM7406 chips all tested fine, so decided to simply rebuild the boards. The vero-board has two additive programmers and a hi-gain pre-amp. Nearly finished wiring it up (only about 80 wires involved).

    Was it non-functional?

    Yes - mainly wires snapped off and hanging loose, plus some shorts to ground. The original wiring was ribbon cable, so quite fragile.
