Thanks tekfan.
The schematics for the 5334b version share similar components designations to the 5334a. Although the B revision integrated the
channel C 1.3GHz prescaler on the main PCB, while on version A, this was on a separate PCB option that connected through a 10pin SIL header.
This is what I've determined about that connector thus far, but the functions of pins 3 and 8 escape me.
1. GND
2. GND
3. ??
4. +15
5. prescaled CLK to mainboard
6. +5
7. -5.2
8. ??
9. GND
10. GND
