I once acquired a ton of calibration equipment from the Tektronix facility in Heerenveen. I need to flip the bulk of it. I want to do at least simple fail / pass tests with these units, but otherwise not touch the calibration. And for that I needed the extra bandwidth.
Enter the first calibration unit: The TG 501 Time Mark Generator.
It does what it says: generate pulses at fixed intervals to calibrate the time base of oscilloscopes
Real vintage stuff. Seal is still in-tact.
TM500 is a Plugin based instrumentation platform by Tektronix.

Man, these guys really loved their plug-ins

The mainframe provides a PNP/NPN transistor pair and two isolated 25 V AC windings for each bay, as well as common 17.5V AC, and common unregulated 11.5 V and +- 33.5V
There's also 30 pins reserved for inter-module communication.
Except you have to wire them up yourself

We are currently using Part-DB and Snipe-IT to manage our stock of components and equipment.

What I really need is some sort of project management / issue tracking, to get my raging ADHD under control.
I've been getting by with lots of folders, text files and spreadsheets and I'm loosing track.

Any suggestions?
Needs to be self-hosted web based, have sub-projects / dependencies, a way to attach files and information, and an overview

The services are running on a lean VPS (think 8€/month), along side the odd game server. I've reached a point where I can't test in production anymore
So let's use kvm/libvirt to run test systems
