freetz Posted September 22, 2018 Share Posted September 22, 2018 Hi everyone, for a small film project, we need to have an old computer with one of these stereotypical monochrome green monitors with blinkling cursor to display some useless information . As I would like to have an ATARI in this project rather than an old PC, I was surprised to see that it is currently not possible to get one of these monochrome green (or even amber) monitors with the Atari/C64 connectors on eBay or elsewhere. So I thought I just take a color monitor and POKE the screen green or code a routine that also adds the other stereotypes such as blinking cursor in the style of the game "Hacker" and the likes. Before I go ahead myself, I was wondering if anyone knows of something like this already existing that would save me some time? Thanks in advance, F.

akator Posted September 23, 2018 Share Posted September 23, 2018 Not sure why you need "Atari/C64" connectors. Both of those computers output composite video. Many "green screens" from the day had a composite video input making them compatible with a wide range of computers. They could even be used as monochrome video monitors although everything would be green. Quote Link to comment Share on other sites More sharing options...
freetz Posted September 23, 2018 Author Share Posted September 23, 2018 Yes, I meant (also) composite, but also HF/TV would be ok, just not Hercules, VGA or anything else that would not run without hardware notifications. That's why I shortened it to "Atari/C64 connector". The problem remains that these monitors (unlike the ST's SM124) are almost impossible to get these days, at least on this side of the pond...

gozar Posted September 23, 2018 Share Posted September 23, 2018 Two pokes will get what you want, but I'm not at my Atari right now to test. Set the hue to green for Graphics 0, with the black and the characters as green. They you wound't have to find a monochrome monitor. If I get a chance, i'll play today, but someone will probably beat me to it. :-) Quote Link to comment Share on other sites More sharing options...
freetz Posted September 23, 2018 Author Share Posted September 23, 2018 Yes, as for the POKEs, I figured these out myself (POKE 710,160:POKE 712,168 for example). But if I have to stick to a LCD display, I was wondering if someone has coded something like this on the Atari so that the LCD screen looks more "retro": https://github.com/Swordfish90/cool-retro-term Quote Link to comment Share on other sites More sharing options...

gozar Posted September 23, 2018 Share Posted September 23, 2018 Then I think you'll need to use one of the emulators that can also simulate CRT effects. Or maybe borrow a CRT. :-) Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted September 23, 2018 Share Posted September 23, 2018 they make devices to add scan lines back in too.... Quote Link to comment Share on other sites More sharing options...
Mathy Posted September 23, 2018 Share Posted September 23, 2018 Hello Freetz Try a Philips CM8833, it has a button that will turn the screen green. Sincerely Mathy 1 Quote Link to comment Share on other sites More sharing options...

I couldn't wait to get rid of the piece of sh*t! Quote Link to comment Share on other sites More sharing options...
freetz Posted September 24, 2018 Author Share Posted September 24, 2018 Yes, an original monitor would be the best option, and especially the CM8833 was an awesome monitor, but it's basically impossible to get these nowadays (without paying like close to 100 Euros). That's why I'm looking for alternatives... Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted September 24, 2018 Share Posted September 24, 2018 (edited) If you don't feel it's cheesy, take any monitor and turn the color pot all the way down, then put a green gel over the screen. (gel is what they call the sheets used on lighting cans) Use any television for that matter... but you can definitely kill the color adjust contrast and brightness and filter it green.. Should work quite well. Get several shades(brightness) of the green you'll find one you like.... You can exaggerate the scan lines for the camera with a ruler and making thin black lines with a fine ball point pen... now that's a 70's green color breakout style.
