An acquaintance just the other day showed me an Arduino experimenters kit that came with breadboard, LEDs, jumpers, etc, all in a compartmentalised plastic box for 28$CDN. Haven't used it myself, just saw it briefly. Maybe you want to start him out at a lower level of logic than that though, or alternatively maybe he can move from that to incorporating & interfacing lower levels of logic.
Something like this, but this is twice the price:
An annoyance of the Rpi for this stuff is the GPIO pins are 3.3V, they need V clamps on input from TTL at least. Not sure where the Arduino fits in that regard.

I have an old Archerkit VOM already, and I’m thinking about turning him loose in August with the discrete components part kit, the VOM, a box of logic parts, and a copy of Horowitz and Hill.

I’ll guess that they both need rebuilding; I have the instruction manuals, though, so maybe that is lesson 1? Is the TekScopes group the best place to find probes for one or both?
