Re: Placing Shelf on Casters for HP Equipment
The HP System I (example: 8640B) chassis system has handles built into the side frame castings, and ears that work with them. The System II (example: 8566, 8350) chassis systems have ears that work

Re: Placing Shelf on Casters for HP Equipment
I understand exactly - I usually work on equipment standing on it's side. The 8566 on the other hand usually winds up upside down - fun and business for my chiropractor :-) Cheers! Bruce Quoting

Re: Placing Shelf on Casters for HP Equipment
Hi Matt You are correct that using a 4 post rack and shelves connecting 2 corners gives added stability but a professional rack has side bracing as part of the rack Paul

Hi Matt Thank you for the link but I personally would hold back from StarTech racks as they do not seem to have an easy facility to put in side runners / side supports The big issue here is are you

Look at the schematics, the step amplifier for example. It shows 2v/div for the steps. Connect an instrument amplifier to the Steps Out and adjust the gain. The deflection amplifiers are trickier but

Re: Placing Shelf on Casters for HP Equipment
Yes, in my experience with the Starcase racks, shelves that attach at all 4 corners to a lot to improve the stability.

Yes, it was 'Point Of Sale' hardware. I bought both minicomputers, ten in counter LASER scanners along with 14 cash registers and 14 printers. Two complete systems, from two stores..They threw in two

Re: Placing Shelf on Casters for HP Equipment
A number of people have mentioned stability without proper loading and braces being a concern for these 4 post racks. It seems like using several shelves that are each fastened to all 4 posts and then

Re: HP 412AR Leads
https://www.radiomuseum.org/r/hp_dc_vacuum_tube_voltmeter.html second photo shows that BNCs can be fit into the holes for the fixed leads.... Might be a nice practical improvement.

Re: HP 412AR Leads
Are they actually coaxial on the 412?? Wow, I didn't realize that. I stand corrected. So, ok, the OP will need to get some coaxial cable rather than single-conductor silicone probe wire. -Dave

I take it POS stands for Point Of Sale, not Piece Of S***.? When I was in engineering school in the 1980s, we used the DEC Pro 350 computers, and they actually had an operating system called pOS!?

Re: HP 412AR Leads
The 412AR dates back to well over half a century ago; you will not likely find "HP 412AR leads". Your best bet is to get some nice silicone-insulated wire and quality alligator clips and build a set

HP 412AR Leads
I picked up a HP 412 AR and the leads were cut off. Where can I find replacements, or build them.
