To the absolute diode sucker who decided to do this to you:
The chip's circuitry uses transistors of 2 sizes, diodes, and resistors. The first photo shows transistors. The different colors are silicon regions that are "doped" with impurities. In the second picture, the diode looks like a transistor with 2 connections. The resistor is a long piece of silicon.

Reverse Engineering a 1960s Diode-Transistor Logic IC
Before transistor-transistor logic (TTL) took over, diode-transistor logic (DTL) was a common sight especially in pre-IC circuits where it was a major improvement over resistor-transistor logic (RTL). That said, it’s …read more

Definitely time for a BiFET lambda diode powered oscillator. Just a lambda diode and an LC resonator, really nice sine wave, too.

blue up the laser diode
looks like they were using pwm to current limit it

This chip uses Diode-Transistor Logic (DTL), a type of circuit that was briefly popular until it was replaced by Transistor-Transistor Logic (TTL), which was faster and more efficient. For this DTL NAND gate, if both inputs are 1, the output is 0. If an input is 0, the output is 1.

You might need to flip the diode and also add some gain with a simple op-amp between smoothing capacitor and comparator.
