Can you run a MODEL 2C CRX in 15khz mode?

[panzeroceania]

Hello chaps,

I recently got a Sega MODEL 2C CRX with Sega Water Ski on ebay and was trying to get it up and running.

It came with a Mainboard, Gameboard, Cage, Video Board, and a Happ power supply (I live in Oregon, USA, and most likely the person that used it before me used it in an arcade in the USA)

In any case I don't have any cabs but I did manage to get the power supply working with a 3 plug power cable I have, and also got 4 BNC connector cables for the video board.

Here is the problem. The board traditionally ran at 24khz, and all I have is a 15khz television.

Does anyone know if you can, and how to put the MODEL 2C CRX w/ Sega Water Ski into 15khz mode?

any information would be greatly appriciated.

No, you'd need a 24kHz to 15 kkHz converter for that (if this one does exist at all)

hmm, or a new monitor. Well that's a shame, thanks for letting me know though.

Once upon a time, Micomsoft made a downscan convertor for this called the XVGA-1v. I have a few that I've used for 24khz PCBs in the past.

The XPC-4 supports 24khz, though it's really expensive.

[panzeroceania]

and when you say the XPC-4 supports 24 khz, you mean it could convert it to 15khz or 31 khz?

All model 2/3 stuff is medium res. That was the pain of buying those boards in the 90s (if you had a cab), they wouldn't even work on an old supergun I had, it only converted low res.

Would a Super Emotia work?

Would upscaling the signal to VGA work? (and maybe scaling it back down to 15khz?)

May be your only option.

Correct. I have never used one personally, but one of the features advertised is that it can accept and convert 24khz video.
The newest firmware revision adds 15khz output, so it should work in theory. Be aware though, it was designed
for old NEC 24khz computers. It does not officially support PCBs so it should work, but may not (similar to the XRGB-3).
Either way it's a very expensive piece of kit. You can probably get 3 or more decent dual-sync monitors for the same price.
