The actual pods, which are plugged into the back of the instrument are
quite complex and have a ceramic hybrid circuit inside. Not the sort of thing
to attempt to replicate. The input to the pod is a pin header with an 
odd spacing. The lead from that to the grabber clips is just wires, so something
could be kludged up

They are much the same instrument -- I think the same manual covers both, Most of the
boards are the same (there may well be different firmware on the CPU board, but I think
that is the only change). The 1631 has an extra PCB at the bottom which contains the custom
input and ADC circuitry to make it act as a digital storage 'scope too.
