Additional Information:
I once serviced this equipment in the late 80s. This is the last of my mainframe stuff I'm trashing.
Today I noticed the frequency of the crystals. Oh wow!, I can re-purpose them for a QRP CW/Digital modes on the Top Band (160 Metre Band).
Guess what, I'm keeping it for parts now. My Wife will be upset, she thought I was cleaning out the basement. Ooops.
