New Model 2 owner!

[SB15SKG]

Hey everyone! I'm brand new to arcade machines outside of MAME emulation, and I went out and bought a SEGA Model 2B-CRX with Sonic The Fighters a few weeks ago and I want to get up and working since it's only a board.

I've literally no idea what I'm doing or where to even start, but the board arrived with broken connections! Hopefully I can also find someone who is able to advise or fix the board at some point so I can get it running.

Hope to speak to some of you in the near future!

Post some Pics…
If it’s the filter board at the front of the metal box, I have spares- so I can help you there.
The pin out pictures are online if you google model 2b pin out
Worth noting that games are 15 / 24 /31khz in general, often called low, medium and hi res.

SEGA used 24khz with the model 2, so if you don’t want to downscale, you need a monitor that can display it.

Best at this stage to deacribe everything you have and what your intending so I or others can give clearer details.

Welcome along, as John says best to get some pics up so we can see what your dealing with, hopefully its only the filter board thats damaged as that will be fairly easy to sort out.

I made a little guide a while ago about making a test bench setup, in short if you dont have a mid res monitor you will need a video converter, something to power the board with and a way of outputting the audio to an amplifier or tv etc, im afraid my giude dosent include controls but they could be rigged up to some buttons and a joystick, all the parts needed are fairly easy to get hold of...

Here's the largest amount of damage, I assume that it's easily replaceable by soldering new connectors on, the other two have a lot of bent pins. Almost half of the plastic standoffs are snapped pretty much in half.

I've not messed around with soldering in a good few years, but I'm currently contacting the seller about the issue. I'm glad to see you guys offering some advice however, which I'm super thankful for.

Dam thats a shame, if you dont have any joy bending the pins back into shape I have a faulty 2b main board buried in the shed somewhere.

Where did you buy the board?

BROKEN BIT: like kev said, you will of course need to fix, but many boards out there do not work, so plenty to pinch the part you need.

You need a filter board that plugs into these sockets, to give the plugs you need to wire up.

And just to note:

Model 2a , 2b, 2c - are game specific. So if you wish to buy additional rom boards for different games, you are limited to 2b, which does have some great games.

If you only want to play joystick games, then you can use a pc running the model2 emulator, and it runs them really well even upscaled.

I bought it from a seller on eBay who's selling a bunch of boards for other machines, and their seller rating was high enough for me to think it would be fine. It did ship inside this large metal box which I assume includes the filter board on the side. I'm not currently in a position to buy any more boards for a while, but I have used the Model 2 emulator in the past which is what drove me to go ahead and buy the real hardware just because I wanted a "real" experience.

Now your experiencing it.

This is what it is like.

I just blew up a £250 monitor chassi
And I’m not in the position to buy another.

Did you get any cables ?Retroman8392022-06-03 13:42:52

I think I saw that one on ebay, if its the one im thinking of I won a world rally from the same seller, although it hasn't arrived yet. Odd the connectors on the inside are damaged, when the filter board on the outside looks ok, anything can happen in transit tho.

On the plus side sonic the fighters is quite rare and hopefully with some soldering you can get it going.

Those Chinese labels are a dead giveaway for yaton. It mightn't have come straight from him, but it is a good bet it was from there originally.

Lots and lots of conversions from there, not that it's a huge deal with model 2 stuff because of easy conversions, but Sonic should have yellow labels.

I sent somebody on here a Jurassic Park in a steel cage, and if I remember right, I padded the inside of the cage too. Leaving any wriggle room in a parcel of exposed electronics is asking for trouble.

Some brilliant games on model 2 though, all the fighters especially like last Bronx, Virtua fighters and fighting vipers.

 

[SB15SKG]

Well it's good to hear that you all seem confident that it will work fine once it's all soldered, however I'm completely lost on specific parts I'd need to get it running, so if there's any sellers here in the UK that you guys recommend, I'd greatly appreciate it.
