74F04
TTL Hex inverter...
http://www.fairchildsemi.com/ds/74/74F04.pdf
Really ancient 74F series TTL logic (F stands for "Fast", which they are, compared with the original "74 Vanilla" series from the 1960's. Also lots more power.) Modern families (74HC, for example) are faster and use much less power. They are pin-compatible, but not necessarily logic-level voltage compatible.
LF411
JFET input OP amp.

Old stuff like this required two power rails (typically +15 and -15 Volts). Output levels could not get closer than a couple of volts from the power supply values.
Modern "rail-to-rail" op amps are available that operate on a single power supply (maybe +5 volts).
TL071
Another old-style FET-input Op Amp

DAC0800
Eight-bit parallel Digital-to-Analog converter. Requires dual supply rails (can work on +5 Volts and -5 Volts) and external OpAmp.

HYB4116
Sixteen Kbit (Yes kilobit, not megabit) dynamic RAM.
With eight of these you can have a whopping 16 KBytes of Memory! I just don't know how the heck you would use it.
The 4116 (developed by Mostek and pirated reverse-engineered by many companies---HYB4116 is an Infineon part number) was a giant step up from the older Intel 2107 (4K bit) device, which never actually worked properly. (In spite of Intel's claims at the time, I still believe that there were pattern sensitivity issues in a significant percentage of the 2107's released into the wild, even though they supposedly tested them at the factory).
This is a really, really (really) obsolete part. Requires a controller to refresh and to take care of address multiplexing drivers. These old NMOS parts (they didn't have large-scale CMOS in those days) require +5 Volt, -5 Volt and -12 Volt power supplies. Compatible with the Intel 8080 and other 1973-vintage components. Maybe you can make jewelry out of them. See Footnote.

Footnote:
For a while, waaay back in the 20th century, it was kind of a techno-fad to make earrings out of electronic components. These were (and still are) guaranteed to make you popular with the opposite sex (unless you are a male).
