Update:
I would still like to get the CLIP, but found two problems:
The option switch on the CPU board was set wrong, and the wires to the LCD contrast pot were broken.? The instrument now seems to be operating just fine.? The LED on the processor board (in the group of 8) is still lit so it may be normal?
Reading a standard capacitor perfectly, and a few others seem good too.
Gotta love repairs like this.

I have the poor quality scan from the Keysight site, but it doesn't include the processor board.
I have a lit up screen with no display.? Power supplies are good.
My unit is serial 2936J09603 which is way later than the range in the manual I have.? The processor board is a much newer design from the layout in the manual.
On power up I get all LEDs on the processor board light up, then they light sequentially, then stop in a pattern of 10000000.? This is the initialization of the LCD, and the troubleshooting guide says the A7 (processor) data acknowledge circuit is faulty.? A CLIP of the processor board sure would help.? I do hear a bunch or relays clicking so the processor is at least talking to other parts of the instrument.
Anyone know where I can find or purchase a CLIP which includes this info?
