I just noticed,  after cleaning a bunch of stuff off my desk,  that the
chips are still in the bag here,  I thought I'd put them in with my other
parts.

Included in that bag are also a couple of red LEDs,  and some other bits including:

2 1N4001 rectifiers
2 small-signal diodes (marked, but I can't make it out even with my
stronger magnifying glass)
2 1N4733 5v/1w zener diodes
1 CA747 (dual op amp?) chip
1 LM3900 (quad comparator?) chip
1 NE565 PLL chip
3 741 op amp chips
2 LM310 buffer chips
1 555 timer chip
1 311 op amp chip
1 LF356 FET-input op amp chip

I wonder what they had in mind when they put this together?
