Everybody who does tech stuff needs a white coat. I remember when I worked for a big food company as a bottom-of-the-org-chart graphic designer, running a DuPont Vaster Design System (anybody remember those? pre-Mac design workstation based on Unix and GPIB.) I had just gotten filthy crawling around behind the console untangling GPIB cables when my boss came in and said the VP wanted to give some visiting Japanese dignitaries a tour of the department. I grabbed a white coat one of the food techs had left behind to cover up my dirty clothes, and gave the visitors a quick demo of the Vaster. Later, after they had left, my boss told me they had told the VP the thing that had impressed them the most about the tour was the opportunity to meet "the scientist" (me!)

I remember using the tester on 2501(punch card reader), 2821(card reader/ punch and printer controller) and 2701(telecommunications controller). Many other controllers had a build in control panel.

I had a 4953A (precursor to the 4957) that died an absolutely horriffic death. One of the daughterboards had a large NiCD battery pack onboard, which violently leaked and destroyed not just the board it was attached to, but several adjacent boards and a decent chunk of the passive backplane. The internals were destroyed beyond repair. It's a very cool looking piece of equipment though, so I retrofit the chassis with an LCD, hand-wired the keyboard matrix with an MCU, and built a cool little portable PC out of it.

Motorola used the TI terminal for remote control of some of their radio equipment which was great until of course the remote modem would lock up and we would have to drive miles away up to the top of a hill, cycle the power and come back. Those were the days! Lol. The other thing that someone mentioned was the size of the return key on the TI Silent Writer, in my experience 90% of the time your using it as a terminal not a typewriter so your choosing from menus with say option 1,2 or 3 or a,b or c, so return was rarely used unless a value needed to be entered which was rare.

Wow! That HP protocol analyzer brings back memories! We had a Honeywell Bull mainframe and its FNP - frontend network processor emulated Burroughs poll / select so we could have a dozen or so ADM-31 terminals on a single port. The FNP would crash occasionally or do something else unexpected. So we had to get the HP protocol analyzer on the line to see what was coming from where. I remember watching that little screen to see the control characters between the mainframe and the terminals. The tape cartridge was handy to play back the screens to analyze what was going on. I don't know what happened to it, but I think we may have leased it for a year. Thanks, Marc and crew for the rest of the stuff.

When storing the IBM LVDA circuit board, I would recommend using a small air tight (Pelican?) container with a desiccant pack and dryness indicator. The main structure is made from a Lithium Magnesium alloy hence the separation of the gray paint. Back in the 1980's, I dissected a rejected Apollo Block II gyroscope. It is built like a precision Swiss watch with tolerances in the sub-microns. The design is based on the MIT/Draper Polaris submarine launched ballistic missile IRIG 25 gyro.
