@RueNahcMohr Yesss love to see some transistor golf. Those fast-on/slow-off (or vice versa) delays have served me well many times as dead time generators in half-bridge switching logic.
(Apparently there's more where that came from:

Vintage Aircraft TTC Dynaplex MULTICODER, PCM - Part No. 711-1272 | eBay
Sparks, NV 89441. 615 Capistrano Dr. Nevada Surplus. This will aide in providing a more accurate quote. This fee will vary depending on the size of the item. Automotive & Aviation Parts.
Nice old-school SMPS too:
More photos, with some General Instruments ICs:
Had an unusually warm couple days here In Montreal recently, so got outside to peel off some more of the potting material from this 60's aircraft telemetry unit with a lot of interesting ICs. Don't expect a writeup on this one for a long time, there's a whole lot of reverse-engineering to do!
@infosecdj Maybe they can hang out with the snakes on my Nortel clock-recovery chip
If you ever wanted a closer look at the high-speed analog-to-digital conversion (8 Gsps!) inside an oscilloscope from a couple decades ago, here's the relevant module from an HP 54845/54846:
