While trying to lay this out this circuit in KiCAD, I realized this had to be the watchdog circuit. After a bit of digging, I eventually found a working subassembly in the 'boneyard' of equipment parts and proved out this section. I ended up swapping this whole section out with a MAX706.

Leaving the diagram up for others wanting to see a non-integrated watchdog circuit that doesn't rely on a 555.
