It MIGHT work as a MultySync monitor with that cable (it seems CGA modes are double scanned - I'm not sure what it does with EGA modes), but I have no way of telling you that. I don't own one of those to test.

option 1) use the ega wonder card and find a real 9 pin cable + EGA/VGA RGB CRT monitor

option 2) find a new isa VGA card that supports my 15pin SVGA monitors

option 3) http://www.ebay.co.uk/itm/D-Sub-VGA-DB9-9-Pin … s-/271747479869 use this adapter to connect my samsung 701N syncmaster

i found this gif that kind of explains how to hook up rgb to modern vga devices
on this ebay auction page: http://www.ebay.ca/itm/15Khz-RGB-CGA-Componen … 1QAAOxyGStRvpjd

ive attached the gif

basically it says u need the db9-db15 cable ASWELL as this funky converter box .. and another normal svga cable to go from the box to the monitor/display

really surprised noone is commenting on this thread..
i guess these topics have been discussed before on vogons and noone wants to talk about them now

The big problem with that is that the arcade world thinks that CGA/EGA is the same as the analog RGB output by most old arcade machines and consoles. It is not.

"The CGA outputs from those arcade game board or older Amiga computers can now be output a desktop LCD monitor for display."

Erm no? An Amiga outputs analog RGB, which has nothing to do with CGA. The signal is basically the same as VGA, just at a lower frequency (no line-doubling).

As mentioned often enough before, a box like this works, but only if you include a custom DAC circuit to convert CGA/EGA's RGBI signals to the proper analog RGB signals.

tbh i dont want to get the box at all!!! its too much effort..
i just want to find an EGA monitor that works with it.. or find a VGA card.. this box is too much effort + im not interested in exploring that in real life i just wanted to see how it worked..

im finding it next to impossible to find an EGA monitor in my area due to the recycling ewaste companies have destroyed all of them i guess

VGA card is the easiest option, and also the best, because VGA is faster and more capable than EGA. Besides, VGA is backward-compatible with EGA too. So you can get EGA on a VGA monitor that way.

hmm looking closer i see the converter boards are kinda cheap.. about 20$? i thought theyd be more

just get a VGA card and be done with it, it's the "proper" card for 386DX anyways - EGA will only limit your choices of software that works fine on a 386DX

i think i need to make a new thread.. with the simpler topic headline/title/question : "what types of displays will work with a 9pin EGA graphics card?"

> "what types of displays will work with a 9pin EGA graphics card?"+

Monochrome, CGA, EGA. Or a VGA Multisync with digital input (Only some really old VGA monitors have that).

That box will only work with a custom DAC (I actually made one of those, I only need the box now for my 8088). Getting a cheap VGA card should be simple.
IMHO unless you want to run software that has compatibility issues with VGA cards (like old CGA stuff - I've never heard of EGA software having issues), an SVGA card is vastly superior because it is not only faster, it will also enable you to use higher color dephts and give you SVGA compatibility.
Also, if you are willing to spend US$20, just spend it here (I assume you are in the US - so I looked for a card in the US).

Mobo

that trident bios looks familiar. i think i might have used a card like that earlier on in life!!
i was kind of intrigued by that rgb retro website claiming that rgb is better for retro gaming consoles...
also i did most of my gaming on the pc on EGA graphics and not SVGA when i was a kid.. SVGA was new.. and really expensive.. i only had EGA/VGA which wasnt as advanced.. but its how i remember the graphics looking when i was a kid.. the idea of getting an ega monitor was appealing to me because of the fact that is what i had when i was a kid.. but of course u are right VGA is superior.. this was the time when i was playing kings quest + Space quest.. and all these sierra games... around 1986-1987 i was 9-10 years old about the time of grade 4/5 in elementary school ... i remember later on i wanted an Amiga computer because it came with built in SVGA graphics.. (not sure which amiga but it must have been sometime between 1988+1990) although im not looking to play these games over and over it would be cool to have the system the way it was when i was 9 years old. working.. i remember very much the difference in EGA over CGA being the biggest jump up in quality... vga was better by alot too. but EGA was still fun + alot more playable then cga!!!!

im from toronto ontario canada area.. about 1 hour north of toronto!!

If you are going to scandouble it, I think your EGA card will look the same in graphics modes as an SVGA card (SVGA/VGA has full backwards compatibility with EGA). IMHO if you can get the cable fast and for cheap, testing it should be harmless and if it doesn't work you can just do something else, like buy one of those Trident cards.
Oh, and for Canada, there is this

this is exactly how i remember gaming when i was like 10 years old! and i loved this game..
i remember being totally obsessed with it.. even being on vacation away from my computer on a trip to the usa all i could think
about was waiting to get back home to try to defeat the wizard + find more ingredients for spells in this game, kings quest 3!!

i didnt have this exact monitor.. but just the look of it.. looks familiar
the slight curvature of the screen

theres something really appealing + Retro about these lower than vga display modes... that show the scanlines etc
at least to someone of my age.. these are really vague memories .. i had alot of differnet computers as a kid..

VGA cards can display lower-than-VGA resolutions (CGA stuff will be scandoubled, and full CGA compatibility depends on the specific card), the biggest factor for that look, though, is the monitor. Unless you find a 15kHz monitor you won't get that look. Using that scandoubling box with a modern monitor WILL eliminate the visible gap between scanlines, for example.

well some news i was able to get the 386dx to output a picture to a television using the composite output of the ega wonder card..
its in monochrome tho... doesnt seem to support color over the composite - either that or i wasnt able to figure out the switch settings

i was able to boot dos + start up windows 3.11 which is installed on the 300mb hard drive

CGA/EGA monitors are exceedingly rare. Most common survivors are IBM 5153s / 5154s. Both command $200 to $500 a piece usually.

There is no real purposes in using EGA. Virtually all software that supports EGA will work 100% correct on VGA. In case you want a retro VGA feel look for a small (12", 14") VGA CRT like the IBM PS/2 series.

Stone on Vintage Computer Forum will sell you a NEC MultiSync CRT that will support MDA / CGA / EGA. However: it will set you back a few $100.

if anyones interested in trading a decent vga card for this "rare" EGA wonder.. it does work.. i havent seen it do color.. but thats because its connected via composite to the tv..
im kind of getting sick looking for vga cards + ega monitors now 😁

yea i dotn want it bad enuff to spend a few 100$
