Looking for monochrome green monitor simulation on the ATARI

[freetz]

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,

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.

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...

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. :-)

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":

LCD screen need scan lines re introduced

[gozar]

Then I think you'll need to use one of the emulators that can also simulate CRT effects. Or maybe borrow a CRT. :-)

they make devices to add scan lines back in too....

Hello Freetz

 

Try a Philips CM8833, it has a button that will turn the screen green.

I used one of these https://www.ebay.com/itm/AMDEK-VIDEO-300A-VIDEO300A-COMPATIBLE-MONITOR-12-Data-Display-1984/192591704380?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D20160323102634%26meid%3D0114e3f91a7f45e491e07eb1d519b496%26pid%3D100623%26rk%3D1%26rkt%3D2%26sd%3D253367102900%26itm%3D192591704380&_trksid=p2047675.c100623.m-1

 

back in the day with my Atari. I couldn't wait to get rid of the piece of sh*t!

[freetz]

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...

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.
