Here’s a supermicro that pissed us off this week. It’s from 2015 and clearly got dumped on us as the result of a certain “text-that-gets-scrolled-on-the-bottom-of-the-news” vendor cleaning out back stock when my workplace ordered a new system.
Blaarffff. It literally seems like the bios doesn’t like certain monitors, and you have to fight it for hours to get video. You’d think with a vendor like Supermicro you’d get a board built with better parts but this thing looks like a damn Soyo. Remember Soyo? They drove themselves out of business by delivering dumpshit. This Supermicro sure looks like overpriced dumpshit complete with “hey look it’s 2001 again” capacitors.
I was at Surplus Stuff and they had two of these Hexem E-I-R meters. They’re beautiful multimeters that were introduced by Belleville-Hexem of Los Gatos, California around 1958.
Google it if you wish but you’ll only find tiny blurbs where it was advertised in a few trade magazines from 1958-1960, and it was recommended by Systron-Donner to calibrate an early chopper stabilized instrumentation amplifier.
Hexem also advertised an “incremental” meter that sounds in concept like a differential voltmeter. This one’s interesting in that it can measure some very high resistances.
And now, we take out two screws in the back and go to look for what batteries it needs. I’m guessing maybe a D and a B (45 volt). Okay, the beautifully built steel case comes apart aaaaaaand
What have I done?!
I’m questioning some of my choices in life about now
There are more battery holders hidden under the shield here?!
Ok, so breaking it down… The RM1R is a 1.34 or 1.5v cell, kinda a 1/3 AA or so. I say 1.34 or 1.5 because I’m unsure if it was supposed to be mercury or alkaline.
Mercury batteries were common in measurement applications through the 1960s as they provided good life and very stable voltage over their lifespan. Of course, they create an toxic ecological disaster and have fallen from use. They’re common in early camera light meters, in which case they can be directly substituted for a zinc-air hearing aid battery with no recalibration required (the change in reading is less than 1/3 f/ stop, which is less than the adjustment steps on any film camera I’ve ever seen!)
The two batteries down in the weird saddle holder would have definitely been LARGE 1.34v mercury cells.
Meanwhile the two common ones are the D cell and the 9v at upper right. Yes I checked the cross reference. The tall cylindrical cells are 6v and N are small alkalines.
This is ridiculous and beautiful and I’m not sure if I’m going to bother acquiring several pounds of uncommon batteries to use it. Uhhhhhhh
After an experience that wanted to make me go SHITPOST ANGRILY I overslept this morning and woke up to the sight of a happy tortie peacefully sunning herself and I couldn’t even be mad anymore over the previous evening’s events that had me stuck up a mountain for hours while a technician for Derp Valley Wireless was ordered to try re-aiming an Ubiquiti radio over and over again because the team down in the office was seeing an RSSI value 2 dB shy of what their link calculations said it should be. Four hours for 2 dB. But look at this tortie. SQUEEEEEEEEEEE
