I don’t actually NEED the e-mail server part, I wonder if there is a build for the e/os without the e-mail sync?

Well the reason the VM is isolated is probably 2 fold,

1. prevent a spread of whatever caused the issue in the first place
2. protect any data on the isolated device for being manipulated and corrupting any forensic evidence that might be on the VM/machine

so if things are done correctly you shouldn’t copy any file to or from the isolated machine

A3.2 and B2.1 in the manual show you the pinouts of that jack and the expected signal, unfortunately section 6.1 schematics and sec D timing diagrams seem to be missing. You’re going to need to find a suitable driver circuit. Without looking at the timing it might accept input from an old MDA adaptor or similar.

Edit: While this in behind a paywall it looks like this old article has a circuit for composite to TTL monochrome that would be what is needed.

This one is from the 1980s itself and there also seem to be a lot of TTL to composite circuits out there that use fairly modern (and a lot fewer) components so with a bit of looking you might find a modern composite to TTL driver circuit. Look at the retro computer and retro arcade game forums, etc.

I don’t know anything about EDM, but since it has to produce very high voltage high current pulses (enough to make plasma in a dielectric tank) and very quickly , the power supply is probably specifically designed for the machine.

The service manual says they were made for an F55 video terminal. 1980s video terminals had video driver boards in them to convert the TTY signals to video. That driver board varied wildly on the output signals, some would output composite video leaving the monitor to control the raster scan, sync, horizontal & vertical sweeps but some would output all of that and there would be minimal circuits in the monitor cage. Hopefully you have ones that take composite video. can you get pictures of the back and sides?

Also, as others have said BE CAREFUL! the crt itself is actually a really big capacitor that can store a lot of potential and deliver a high voltage zap long after it is unplugged. While it’s running the fly back circuit produces 1KV (1000 volts) or more so I say again BE CAREFUL.

It’s a “safety capacitor” used across AC, similar to a Y cap, they have a known failure mode that is designed to not cause fire.

Honestly this is not worth the risk, It looks like a simple enough repair a high watt resister a cap and possibly an IC (U1 looks burnt) BUT consider this, something happened to cause the failure and that something could still be around, like a short in the heating element of the throw. Whoever designed this obviously did not test the failure mode of the device. The reason things are UL rated (other certs for non US) is that they get tested and found to not fail in a manor that will cause harm to the user or fire. The failure mode of this device could cause a fire, if you repair it and the same thing happens. . . . Don’t risk it, Toss it out.

ALSO NOTE! if you do attempt it. That cap is most likely a class X2 cap and would need to be replaced with the same, don’t use just any cap!

Get into Ham Radio, not just get a license and talk, get into it. make your own radio, antennas, learn the science, learn firmware programming and microcontrollers, everywhere you turn there is something new to learn and puzzle at. And you can help with community service things (only if you want to). It’s great because you can go as deep as you want (or as shallow), keep your mind engaged and have fun doing it.

From my perspective, Keep it. You should ask your SO though.

Picked a fine day to quit sniffing glue.

I looked at the trap Ray.

Be excellent to each other!

When will then be now? Soon.

Give me a ping, Vasili. One ping only, please

It’s a i5-8600 3.1 Ghz 6-core.

as others have said it’s a pre release sample for testing and might have bugs but the QP4W tells you the processor type
