Although it came together as team work in the end, I like to think I was the person who really got it started.
I went to the bother of buying two used Tek PSU's that I didn't even need at the time just for the sake of reverse engineering the thing.
Many hours spent...
As for spare PCB's ISTR someone mentioned having some here or on the LeCroy group about a year back.
I must still have my original layout somewhere if you want to try a DIY PCB, it's a single sided design with 0Ω SMD's where jumpers are required.
