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.p or similar.
- Comment on What is special about a power supply designed for basic EDM? 2 weeks ago:
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.
- Comment on Question about driving some 80's CRTs 2 weeks ago:
The service manual says they were made for an F55 video terminal. 1980s video terminals had video driver boards in them to con vert the TTY signals to video. That driver boards 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 tharpt take composite video. can you get pictures of the back and sides?

I also saw where they used a graphic of the entire US when the study only encompasses 1 county in California.

Look at the map this is just higher near larger population, Correlation vs. Causation. This smells like bull shit.
- Comment on Is this soldered controller repairable by an amateur? 1 month ago:
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.

It’s a i5-8600 3.14 Mhz 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

Done them all and I see 4 that still apply today.

Was that a Dominos pizza sponsored game? I seem to remember “Avoid the noid” was a slogan of theirs.
- Comment on Reverse Osmosis water system for sink and fridge 6 months ago:
I’ve got this one for almost 4 year and have been happy with it.

I have it hooked up to the fridge and a RO tap by the sink. a couple of things I would tell you is get a bigger tank that what it comes with (2.5 gal). And don’t install it under the sink because it’s hard to get at the filters to change them and the pump can be noisy when refilling the tank.
