First IC you came in contact with?

Silveruser:
First ics 7400 family, first CPU 8008 with RAM by the square foot????

In the early eighties my dad already had a good selection of CMOS, TTLs and linear ICs, but one of the first IC-based projects was using a CD4011 from Signetics - a "perpetual" LED blinker, followed by sequential LED blinkers using cascaded CD4017 ICs.

The first programmable device was a Z80 inside a TK82C from Microdigital (ZX81 Brazilian clone).

As for the first transistor, probably a BC547 or an AC126 (on a Philips Electronics kit).

We built a log amplifier, and the teacher was screaming us: "this device cost an arm and a leg, so please be really careful".
We used a socket, so the IC will not be damaged by our "fire sticker" soldering iron with pure copper tip, to be filed before each use, and then the IC could be saved and used by other students.
Good memories..

Fairchild uA709's, remember them well  they were Round (~3/8" diam) with  shiny black epoxy tops and white sidewalls with a index flat and had red and black printing and gold leads.   I think these were the very first gen 709's that were ever created.  I can't remember if the F8 processor was before or after my experience to the 709.

Original 7400 series ICs in 1970.

AG6QR:
During my second year of college I came into fairly close contact with the Z-80 microprocessor (programming it in assembly using a Northstar Horizon), the 741 op-amp (tinkering with a Radio Shack kit for an audio reverb effects machine), and many members of the 74LS series of TTL logic (in a computer architecture class, with lots of labs, involving wiring together gates to make a CPU).  I can't quite remember which of those was first, but they were all nearly simultaneous for me.  The 555 was in there somewhere, too.
