Just out of curiosity, what's the speed rating of your 1230? My HP 1651B can
do 25MHz state and 100MHz timing.
I suppose I can always try IDC cable. It's not exactly expensive stuff and
there's a good chance of it actually working. If I can't get any HP probes
and the seller won't refund me for the analyser, it's always an option.

I suppose the same thing happens to oscilloscopes. My Tek 466 still needs
another probe - Tek part number P6062B.

The HP probes use a custom analog IC, but the innards of said IC have been
published in an appnote. Replacing it is possible - just use two resistors
and a capacitor.

In my experience, I'll probably get negative feedback for requesting a full
refund, but I guess it's worth a shot.
Later.
