I thought that they were 1N821 series or similar TC compensated discrete
zeners ( series stack of a zener chip plus one or more forward biased
diodes all in same hermetically sealed package)?
IIRC thats what the manual states.
I have datasheets for most of the Motorola TC zeners if thats what you need.
