The five HP racks I have are all the same: equipment space height = 1425mm = 32 U.
I was never able to find a part number or other mention in any old HP catalog.
Some pics of the ones I have here: Whole racks, Detail.
Originally the ones in my pics did not have castor wheels - I added those.
The reason I need this exact rack in particular, is that I have five of them and space in the row for one more, but only one of these. My workshop room just happens to fit six of these in a row along one wall, but not an inch wider. Due to their design these have very little excess size over the 19" equipment they contain. Each rack frame is just 536mm wide. That's only 25mm more on each side of a 19" rackmount instrument's mounting brackets. Modern racks are never that compact, so they absolutely don't fit in the one remaining rack space in my lab.
Also, it would be nice if the row of racks matched.
These racks consist of diecast top and bottom frames, and four extruded aluminum vertical struts. The frames bolt to the struts with large hex-head machine screws; 4 each at top and bottom. Getting those undone requires a really big allen key - 5/8" A/F.
Then there are various essential small bits such as the nut-strips that slide into the vertical struts. (They take UNF #10 screws.) Also the top cover. There are sometimes side sheets, but they're optional. If I can find one locally with them, great. Otherwise, doesn't matter.
I need one of these so badly I'd even pay for shipping from the USA. It would have to be disassembled and packed in two parts (the frames in one, the struts in the other), but my US reshipper could handle the resulting large parcels.
5062-3984 (4U 7", 177mm) obsolete, replaced by:
5063-9222 obsolete, replaced by: 1CP013A
Don't really care what color, though the more recent ones with light beige handles look nicer.
Gosh, it's hard to find 4U handles! Ebay often has other sizes, but 4U seem to be unobtainium.
- PC software for HP 3567A FFT analyzer. (Yet to see if the 720K disks I have are readable.)
- Double sheath screw co-ax connectors mating with those on rear of 3567A 35652B plugins. And tri-ax coaxial cable?
This is the connector:
I have some such connector blocks, but without shrouds, and pins in wrong places.
Also need the special tool for pin removal.
Attempted to make one from brass tube - not very successful. Tool needs to be a very thin-walled.
but tough tube of exactly right ID and OD.
Normally I just rip out odd power connectors and replace with standard IEC fittings.
But on this instrument it seems sacreligious.
The GRC connector is not a problem. Of course nowadays there are ways to get higher bandwidth optical sensing, but I can't afford things like HP fibre communications scopes. Also I'd love to have a look inside one of these. Quote:
Update: I did find one, but it's missing the diffuser glass. See A 1970s High Speed Optical Detector.
Here's an example; the facia of a Tek 7000 series scope plugin. The effect is very nice, it's a smooth satin hard surface, with absolutely no surface height variation due to the inks. Like all anodized aluminum it's very hard-wearing, nearly as tough as glass. Dirt, gum and stains can be easily cleaned off without marking the surface at all. The inks are embedded inside the surface, so are as tough as the whole surface.
