On unrelated news: The -hp- 4952A with some photos (outside only at the moment), more to come...
Wow, what a surprise ! Didn't think I would see one of these here !
That reminds me of course that... I have one too... unloved for now
Well it's not 100% the same as yours, but looks the same. It's a 4951C
Got it 2 years ago, offered for free (paid only 10 Euros for shipping), by a guy I bought a Tek 2214 scope from.
He showed me this HP protocol analyzer, saying he would never be able to sell it, yet could not resort to throw it away, so he asked me if I wanted to have it.
I didn't have the heart to say no, of course. I mean it's HP, and it looked so cute I found, in this compact portable form factor with that lovely keyboard and green CRT screen... and floppy drive !
Plus it can do RS232, and I like RS232. So I thought well I guess I could find a use for it, try to connect it to some TE's serial port, I don't know... was trying to find excuses to justify rescuing it.
The CRT is badly burned, like yours with horizontal stripes. But somehow once you turn the instrument on and there is stuff displayed on the screen, the brain doesn't notice as much...
Plus, the instrument has a video composite BNC connector at the back for an external monitor, so I was thinking of trying to find a way to hook up a monitor to that. IIRC it's NTSC format so not French friendly.
We don't do NTSC over here... but at the time I searched a bit and found there are cheap video converters out there that can take a range of video connectors and standards, and spit out in a number of formats as well. So I thought worse case, these gizmos could save my bacon.
Believe it or not, turns out I have no pictures of my unit ! Only pics that the seller put on his ad back then.
I did apparently however, take 3 pics of the mini tear down I did of the pod.
Oh, forgot... other than the burned screen, it's also missing the interface cable that lets you connect the pod to the instrument !
so... not much use.
Somehow on mine, just like yours, as you can see, the space bar is heavily yellowed but all the other keys are fine.. strange.
