The Wayback Machine RGB thread is one of them.
This one is very popular as well: https://shmups.system11.org/viewtopic.php?f=6&t=56155

Merry Xmas everyone! Or whichever way you celebrate too.

Chances are you'll eventually tear up something, or at least do a sloppy job and want to re-do it eventually, I did quite a bit in the early stages of the learning process. By the way I always use 105 degree Nichicon capacitors. Avoid oddly-branded Chinese caps at all cost.

Hi Jon
In this case the caps are for "coupling". They pass the "AC" part of the
signal & block DC. Caps to ground are usually for "decoupling".
They pass varying signals to ground to keep B+ lines as clean as needed.
They "save" voltage & let it go when needed as the B+ sinks.

Ah yes, that first part occurred to me not long after making that post, I thought it an odd place to use an electrolytic. The "negative towards the TV" part threw me at first.

I can hardly wait to get restarted on my own set's repairs, the weird waveform on the convergence board has me stumped at the moment.

The reference to electron theory vs conventional theory is about the direction electrons flow. + to - or - to +. Convincing arguements both ways.
Anyway,...not that relevant I guess.
I'm familiar with Nichicon, Rubycon, etc. I am a career master auto tech and I never use cheap parts if there is any way at all possible not to.
I bought several of the pre-made cap kits for my old videogame consoles and recently I discovered a depot place in Fla. that sells caps (not cheap ones) in bulk. So I am good to go in that dept. after buying a huge assortment priced right.

P.S.- I will post pix of the Sega running when I get this figured out.

Hi, did you ever get this EIAJ connector sorted out? I have a Sears LXI model 564-40843652 that I’m interested in utilizing that port for analog video.

That connector is used on a lot of japanese TVs that were sold as monitors. The Sony's have them from that time period. It's probably the same pinout, but if it was me, I'd just open it up and check where each pin was going to inside.
The Sony standard can be found online in the Operator Manual for the CPD-9000/1201

Just noticed this since someone necro posted the thread. What is "The Wayback Machine RGB thread?"

I'm a regular contributor to the Shmups forum, so I know about that, but I never saw whatever thread you are talking about on the Wayback Machine.

Hi, I got the pinout from here: https://www.minuszerodegrees.net/man...%20Pinouts.jpg someone posted it earlier on in this thread.

Was just curious if anyone has been successful in using this port for RGB input and if so how the cable connection process works.

I do use one with my Sony CPD-9000. It works very, very well. They made cables that go from EIAJ (which is what is on the LXI) to DE9 (which is the same as CGA/EGA).

Of course, it would depend on what your source was. Now that you have the pinout, you just make the outputs go to your inputs.

That’s great to hear. Thank you. What is your source? I ordered an EJIA to CGA from Bulgaria about a week ago. I’d like to adapt it to use a Sega Genesis, SNES, & NES as sources.

The correct cable came with my monitor when I purchased it. Otherwise, I would just purchase an EAIJ connector end and built my own cable.

If you have CGA on the end of the cable, you'll have to build a new cable that goes from another CGA connector to mate with the one on the cable you ordered. The other end will have to terminate in whatever you have outputting from your consoles. Hopefully they are all the same or you will be building a lot of adapters

The LXI tv is actually advertised as a tv&monitor. See pic.
And,.... the input is digital rgb, so Sega, etc. unfortunately are not compatible.


This is years ago now but not long after this thread I scored a connector from
an indie tv station here. See pics.
***Shout Out to Elliot Block(R.I.P.) from TV 25, an indie channel in Cincinnati.
In the '90s they were a total guy channel, called Network One.
It had original ECW wrestling , Japanime with pixelated nudity, otherwise uncut and Venus Swimwear competitions among others.
This guy was The Man and I feel privileged to have hung out with him for a short bit.

Just curious. What kind of setup (rig) do you have for your monitor?
Classic IBM compatible DOS? Amiga?

I have that particular monitor being fed by a Chromecast through an HDMI->VGA adapter, and the to an Extron VPS700 to get 480i output (resized to fit properly and comb filtered) so that I can watch old 4:3 TV shows in the kitchen.

No joke.

I don't actually keep much in the way of old computers going tbh. I own a couple old 486 things, but I really never use them. As far as I'm concerned, the only important part is that I can use the correct monitors and the correct keyboards. The rest is just an inconvenience.

I grew up with a XT, playing old Sierra games on a 9" amber monitor through a Hercules card. Then a 386SX and a VGA monitor. both were huge steps up from the last, but they were still so unbelievably slow.

I was so happy to get rid of those old things and move onto something that was more capable that I don't really get what people are so happy about messing with them anymore. Yes, I had plenty of fun with them, but I already did that. I don't see an imperative reason to dial the clock back to inconvenience myself with that stuff again when I have great new stuff I can use with emulation.

I fell the same about tapes (K7, reel-to-reel). I ended selling the ones that I had recently, in a attempt to play with. The hassle about the mechs and tapes...
In any case, I selled it for people just wanting to play with. Hence, tastes and tastes... for some will be the holy grail of ancient electronic fun.
I just prefer vinyl and digital (for audio), and some TV's for a small collection.

Ok, thank you I will give it a shot.

Nostalgia for me. I also find the designs & forms more ascetically pleasing.
