It just so happens that I have just purchased szu's monitor on eBay.
Apparently, szu was looking for help in getting the right cable in order to snap pictures for the auction.
But don't worry, I'm not here to claim "lemon!" (Yuk, get it?) In fact, far from it. It's a really nice monitor, and it survived the trip all the way from Michigan to Anchorage. However, I'm having...not dissimilar issues!
Oh, I know all about the Y/C video cable, and have made a few myself, and I'm just fine with THAT input. My question is regarding the mysterious RGB port, which legend has it will allow a Commodore 128's RGBI output to hook up to it.
I'm unable to find anything on the net regarding the pinout for this port, as it's different from the DIN-8 that the Commodore 1084 series monitors uses (which I have one of also). When I tried that cable, I got no results, just a dark screen.
I did some research on the net today, and I found a site that at least explained what the different "modes" are in the mysterious Mode I/Mode III switch...according to the site, Mode I is CGA-style RGBI, Mode II is Apple IIgs style analog RGB (not present on monitor) and Mode III is Apple III-style digital XRGB.
Based on this, I'm assuming I can't wire up a custom cable to use the analog outputs of my Amiga with the monitor, but I'd be perfectly happy to use it with the C128...IF I can get the pinout.
Research today also led me to the following Mode I DIN-8 pinout which I tried:
1 - Intensity
2 - Red
3 - Green
4 - Blue
5,6 - Ground
7 - Horizontal/Composite Sync
8 - Vertical Sync
You'll note it differs from the DIN-8 for the 1084s, in that pins 1 and 5 are swapped. However, when I wired up a DB-9 to DIN-8 cable at work per this pinout and tried it at home tonight, I still get nothing....almost. If I fill the 80-column screen with text, I can see horizontal and vertical bands of noise, in blue and red, and just a hint of the green text, as if it were an analog channel tuned in very poorly.
Wondering if it was the addition of vertical sync -- I've actually had some issues with "sync" in dealing with Amiga analog video to RGB converters, and I removed the vertical sync and tried it out...and now there's only a vertical stripe of blue "interference"! What the heck? If that wasn't vertical sync but BLUE, then the CGA-ish pinout I've been following is WAY off.
Anyway, I see mentions on other forums of people with this monitor, the Teknika MJ-22, saying "they got a service manual" or "they got a pinout", but my Google-fu has come up dry. There's even a cable for sale online that'll supposedly work for $7 mentioning this exact brand of monitor, but...c'mon! Hasn't ANYONE got the pinout for this, so I can just wire my own cable? Any hints or help appreciated! If anyone has a DB-9 to DIN-8 cable for this monitor pre-made, can you tone it out and tell me the pinouts?
