Thanks, I will go on monitoring until Monday then (I am off to Munich for Xmas after and don't want to let it run unsupervised as I still have to recap). Have a lot of parts on my desk including a new front which should restore it to its former glory. Project for after Xmas. Have also modified WinGPIB (thanks Ian!) for NI GBIP-232CT-A use, will share that back in case anybody needs it.

Frohe Weihnachten and many thanks for the support so far!

On another note, is it possible to get the nuts off the binding posts and/or change out the red rings? I bought two of the fused ones fixing one of my damaged ones in the process but the guard terminal is still missing its ring. A new terminal block is a whopping 473 GBP plus VAT from Keysight, bit steep for a red ring :-)...

Looking forward to integrating your mods back to my master, just send me your source and details when you can.

So recapped outgard today (C1/11 were leaking) and socketed the chips on A5 - direct read of the CALRAM yielded something different than WINGPIB - need to research that a bit. Still waiting for the boards to do the FRAM conversion. Next step is to give it a good scrubdown and recap the inguard PS, internals are surprisingly clean. Sadly only got three feet from KS, still wating for five more :-).
@Ian: will mail the changed files later on.

IanJ:
Interested in the Calram differences, can you email me both hex files?
When I did my 3458A I used the WinGPIB generated one (which matched the DOS app one also) and it was fine……..so am interested in why your direct read is different.
