Wouldn't it just be easier to throw in an NEC multisync? It does SOG, cga, ega, mcga etc. And alot of them even have the bnc connections required on back.
Yeah, that's what I think, that it's an RGBS monitor and the confusing labels of RGBW in one post and RGBI in another are just red herrings, especially if the fourth coax cable goes to one or both of the monitor pins R2 and R3. Too much incomplete, confusing and contradictory information making a mountain out of a molehill IMHO.Looking back at the pictures you posted earlier... What is the word printed on the PCB below this connector?
It looks like it says "SYNC"
If this is true, then you have Red, Green, Blue and Sync.
A grand for an LCD monitor???
Yeah, I was thinking more of a normal LCD monitor with a converter, once we finally nail down just exactly what we're dealing with. There are dozens if not hundreds of them out there, as well as many different BNC to [whatever] cables, but these days many are for VGA input, not 15KHz NTSC RGBS.check on ebay for NEC Multisync monitors with RGB inputs. yes. I have tried craigslist, with no success. All close to me are vga connectors and no ones with BNC.
The markings on the cable don't mean much, if anything; as Ian says, what matters is what it says beside the BNC jacks on the computer end and, if anything, at the old monitor.The "I" and the "W" are on the cables with wire marker. They are marked at the board and at the place where they splice to the Hirose connector wiring. That is why the confusing I and W posts.
Hope someone else is paying ;-) But you may end up using the VGA LCD.Part of the thousand I am into the project is the first LCD VGA, a CM-1, and the CM-5 and the shipping for one of them. The site is an hour away and parking hits me for $25 a pop with the four visits I have had there so far.
Sorry, what exactly are you giving a whirl this time? Must be getting pretty frustrating..I guess this weekend I will head over with the other monitor and give this one a whirl.
It has occurred to me that we're speculating a whole bunch.
Ya reckon? ;-)It has occurred to me that we're speculating a whole bunch.
...now there's an image...It seems to me that we're poking at elephants with our eyes closed.
So far, he's tried to connect two monitors, both incompatible with CGA video frequencies, and has not gotten it to work. He's ruled out VGA (which, considering it didn't come into being until 1987, is not at all suprising) and the obscure Tandy 2000 video modes.
I think if he actually tries using a digital CGA monitor (or at least one that supports 15.75khz video), then he has a pretty good shot of getting it to work.

Well, I've asked a couple of times but no answer so far; somewhere there was a cable that shared a shield that went somewhere, then there were brown and white sync wires somewhere, we don't know if that BNC is really labelled SYNC after all this, etc.; I'm getting a headache... ;-)...We need to see the inside of the Hirose connector on the original cable and then we would know what the 4th BNC signal really is and if there was any jumpering going on internally.
The CM-5 is a CGA monitor with a 15.750 KHz HSync frequency, so, not too incompatible with CGA frequencies, I'd say.
...and some confusion ;-)well, some more info to add to the mix...lol.
You tend to be a little vague; it's my understanding that aside from R/G/B there's only one other signal coming from the system, so where are you getting Intensity and Sync(S) from? And exactly what cable/pin/connector are you connecting where? And do we know the CM-5 works?I tried the CM-5 monitor. I got nothing. I tried with only RGB, then with the others connected (intensity and sync's) and still no result.
Sounds like composite sync; have you got a TV or monitor with a composite input (the yellow RCA plug/jack) by any chance?I did notice on the board that where it said sync it also said B/W under it.
