In the 5370B manual (2940A prefix), it looks like they are running U7 from
+5 on pin 3 and -5.2 on pin 12. Probably a drafting error in the -A manual.

Fix for yet another typo, I really should check the text more carefully.
The positive supply connection to A22:U6 (LM339 quad comparator) is
shown as ground in the circuit diagram.
This is surely incorrect as the inputs of U6B and U6C are connected to
TTL(+5V VCC) signals.
Surely this is not th

The positive supply connection to A22:U7 (LM339 quad comparator) is
shown as ground in the circuit diagram.
This is surely incorrect as the inputs of U6B and U6C are connected to
