looking through some old photos, i found some neat pictures of IC chips. this one is a 7805 regulator.

8755 16K EPROM + GPIO

Intel 8080 CPU.

(this one is from National, i think they were a mask licensee)

Mostek 4116 - 16kbit DRAM

LM113 voltage reference. you can count the transistors!

Intel 4201 clock generator (for the 4040 CPU)

here's the Intel 1702, the first commercial EPROM chip.

intel 4289 standard memory interface. (for the 4040 CPU.) note the bizarre damaged bond wire and repair (with solder!)

AM2909 bit-slice address sequencer from AMD.

SP3725QD quad NPN transistor array. each transistor is a separate die!

AM2812 32x8 FIFO RAM (with bonus serial in and out!)

National Semiconductor 7438 quad 2-input NAND gate. buffered, open collector output. the lower left corner is missing due to my primitive decapping technique 🔨
