I will never stop being amazed by your professional reviews of hole warmers, probe attachments and other interesting stuff. Perfect!

That power supply seems to be from a VAX 11/750 or related mainframe. There appears to be 2 different power supply boxes, like 2.5 and 5 volts. I have seen some documents about the mainframe, and just found the motherload on that part:

Further reviews of that multimeter should include a 600 V very low impedance supply, a CDN and an 8 kV transient source.

I would suggest blast shields and a slow motion camera
