Has anyone here used a monochrome phosphor CRT with a modern machine? Say, a monitor with a 9-pin serial/re9/rs232 cable with a more modern PC. Also, this will just be a terminal screen. Possibly with w3m images. Here are some options I've thought up. I haven't picked out a monitor yet.

VGA/serial adaptor

These adapters are common. Don't know if they would work.

CGA video card output or other period correct, oem matched card

Don't know how the fuck I would use this on a modern board.

Some other 9 pin display video output

Maybe there is an old PC with Core Duo or Pentium with serial display? I was born in '96, so I'm not too savvy on 20 year old graphics hardware

I know that the green Macintosh CRT's are pretty cheap and use a 9-pin, but the pin out is proprietary. Chime in if you have experience with these things! Am I over thinking this?

That's a nice idea. I used an amber Hercules CRT until 2007, or so. If I wanted to go for the ancient hacker theme today, I'd probably use a full terminal rather than only a monitor. For a monitor you would have to build your own adapter or use an old computer to drive it. A serial terminal would work with a much simpler adapter or directly with a USB-RS232 adapter or the console header on a modern motherboard.

I overlooked using the actual terminal. Probably the best option.

lol you're fucking retarded. You're staring at CRT. You're not blasting plasma into your face.

A CRT built in the 70s-80s is a bit different

I've decided to just buy myself a DEC/Boundless VT520-BA terminal w/LK412 keyboard and hook it up to my freebsd rpi2. null modem cable is like $6.

520's are still made to this day funny enough. Pretty confident x-rays will not be problem. Nor gamma. Don't really care.

About the only thing your going to be able to use on a modern computer would be a composite monitor because you can get VGA->composite adapters.

The 9 pin monitors you see are not RS232 even though they are DB9 plugs. When these where in use RS232 was actually DB25.

Monitors that used DB9 on the PCs where

<Mono

>MDA

>Hercules

<Color

>CGA

>TGA Tandy's extension to IBM's CGA

>EGA

These use a bunch of TTL signals so there is no way to really connect them to a modern PC with out some custom hardware hacking to convert the signal types.

Same goes for the MAC. Its a 15pin connector and the signaling is nothing like VGA. So you would need hardware to do the conversion..

IBM did make mono VGA monitors that where really sharp. I think they where for the PS/2 line.

Like someone else said above your best bet is to hunt down an old dumb terminal like a WYSE or DEC. They where used all the way up until the early 2000's in retail and industrial settings.

Thanks a lot everyone for helping me figure this out!

VT550 ass-end in pic. You can get null modem/crossover cords for like five to six dollars for 6, 9, and 15 pin plugs. Seems easy enough to do if you have pinout charts for the correct plug variant.

I'm going with a terminal now. Makes sense anyways since I planned on using it for a BSD system (freebsd rpi2b)

What about using an entire old PC running a terminal emulator, or more perverse yet, an X Terminal client served off modern Linux?

>>830946

I dunno about the other stuff, but Mac and *N*X workstation monitors were commonly used with VGA adapters, of which there are zillions floating around on the secondhand market to this day for a pittance.

the flickering alone is a big problem for eyes/brain.

unless it has really slow reaction and you are doing 150+Hz scans.

Reported for reposting a thumbnail image.

You should be banned because you did it for a thread picture, you quintuple-nigger.

There is absolutely no flicker on old high-persistence phosphor monitors because the phosphor retains the signal for longer than it takes to update it.

Is this a thing now? Just reporting people for random things we don't like that aren't even tangentially mentioned in the rules? Doesn't this just piss the mods off?


▶ No.831963

>>830651 (OP)

I think you could probably change the color settings on a standard crt so that the image is monochrome. It works on my $3 dell one anyway.
