We COULD have an interesting discussion on just what this collection of
parts would look like, especially for a "mostly micros" development setup...

ICs:
74hc595 "output expander"
74hc00  nand gates
74hc373 latch
??????  optoisolators?
7805    5V regulator
317     variable regulator
??????  op amp
PIC12F675 or
ATtiny12   8-pin micro
PIC16F628 18-pin micro or...
at90s2313 20-pin micro
PIC16F876
ATmega8
ATtiny28  28-pin micro
PIC16F877
ATmega32  40-pin micro

Diodes:
1n4148 general purpose signal diode
1n4007 general purpose 1A rectfier
?????  general purpose schotky

Transistors:
2n2222a  general purpose NPN
2n2907a  general purpose PNP
MJE3055T? GP NPN high-power
MJE2955T? GP PNP high-power
??????   GP N-chan logic-level mosfet
??????   GP P-chan logic-level mosfet
??????   GP Triac

Resistors:
One 'most values' assortment (10 resistors per.)
extra of 1k, 10k, 100k
0.1, 1, 10 ohm power resistors

Caps:
.1uf, .01uf      bypass caps
22pf?            crystal caps
1uf, 10uF, 100uF electrolytics

An assortment of wall-warts.  Or perhaps a bunch of "universal" wallwarts.
Battery holders.  And some assorted batteries, of course.
Relays.
LEDs.
Switches: toggle, pushbutton, key?, reed?
Noise-makers.
crystals and/or ceramic resonators.
photodiodes and/or LDR light sensors.
LCD dot matrix displays, surplus
LED 7-segment displays
