Hi

I am looking for schematic of Tektronix COMM PACK 1200C11 for 124x Logic Analyzers

I have the COMM PACK but it doesnt work and I can see that someone had modified it - lots of solder and cut traces on the PCB

Took awhile to find it on eBay and now I am stuck

Will be happy to trade manuals... I have ops and service

Thanks
B
