    Virtual Ribbon - The Permanent Virtual Boy Eye Fix by SSFD

    I have a Vboy that needs some work in general. How much for the services for a v3.3?

    Sega Model2/3 - JAMMA Adapter Thread

    Sorry for taking so long to update this but my work area had been claimed by the rest of the family for the holidays. Anyway, this weekend I plan to finish assembling the first PCB I've been working on and test it. Considering the audio works, I can only assume my reverse engineered traces...

    After several failed attempts, Digikey has sent me the correct parts and I can finish these damn adapters! lol

    Sega Model2/3 - JAMMA Adapter Thread

    Now imagine being an arcade operator where a "long session" means the unit is on from before opening to after closing. That's the kinda thing I'm worried about.

    That assumes I pick the right Mini Fit Jr connectors ||

    Sega Model2/3 - JAMMA Adapter Thread

    Well, I've been thinking, and why don't I just make a board that handles the RGB, Input/Outputs, and an amplifier for the JAMMA portion and then just make universal adapter cables for power? Like maybe AMP UP connectors that I can distribute to the power board and then just build a connector to...

    Just exchanged a few emails with Ken over at irepairsega. What he had to say was quite alarming and makes me want to abandon this project: Also in regards to telling Ken I use a 5v 10a in my setup outside my cabinet:

    Sega Model2/3 - JAMMA Adapter Thread

    Ah, thanks! So my header supplier accidentally keeps sending me the wrong 10-pin headers, so I don't have a completed unit to test yet. But in the mean-time, here are some comparison shots of both boards with the amps on them. I feel like the old board was sloppy as it didn't have capacitor...

    So I pulled some images from ebay and overlayed them. This is a super simple circut, but I'd like the exact resistance value for those resistors to be honest. I'll cross reference this with the SpikeOut schematic to better understand what's needed: Thanks!

    Sega Model2/3 - JAMMA Adapter Thread

    Please do, those are a little small to get the details fully understood. Not the ones I am currently making, no, but we are all working here together so I can understand how to make an adapter that is both Model2 and Model3 compatible with a JAMMA cab. So hold out a bit longer please as we iron...

    Sega Model2/3 - JAMMA Adapter Thread

    Ah yes, see my EDIT3 above! Stereo is working! Left channel out of Speaker +/- (10/L) and right channel out of Coin Counter 1/2 (8/J), so if you want to wire this up for stereo, make sure your cab is wired accordingly and that you do not use a coin counter through your JAMMA harness. EDIT: Got...

    8o 8o 8o 8o 8o The new board is slick af! I paid quite a bit extra on the JLPCB site for some of the better stuff and it sooo looks worth it! EDIT: GOOD NEWS: It amplifies audio, and it sounds amazing! BAD NEWS: It only amplifies one channel. WORSE NEWS: The mono resistor fails to mix...

    Sega Model2/3 - JAMMA Adapter Thread

    Oh ahahaha, I meant that two PSU's out of the box are normally not tied together, but yes, they should be tied, but I'm not quite sure how to go about that? Would that be outside the confines of a JAMMA adapter? Oh wow! Thank you for your interest and that's extremely generous of you! That would...

    Sega Model2/3 - JAMMA Adapter Thread

    Ah, gotcha. Fair point. And since all the pins are used I guess that changes how I'm gonna lay this thing out a bit. Now my next issue here is to handle the GND. Obviously if we've got one PSU for the JAMMA and one PSU for the 3.3v, they don't share a common ground, do they?

    Sega Model2/3 - JAMMA Adapter Thread

    If that's the case, I really wonder if I could tap into the 12v rail for a 3.3v output on the JAMMA adapter. Damn I wish I had a Model3 to test but I don't. I found another Model2/3 JAMMA adapter from coinopexpress but it looks severely sketchy. There are several of them up on ebay as well...

    Sega Model2/3 - JAMMA Adapter Thread

    I'm seeing a little more viability now. That being said, however, I am by no means an engineer (I just play one on the internet). I don't know that I could properly lay out such a thing. And am I understanding that the 12V connector is just for the fans? Is that why it's only a few pins compared...

    Sega Model2/3 - JAMMA Adapter Thread

    I've had a few days now to mull this over, and basically everything in my head points to "If you're running a Model3 you probably shouldn't be trying to run it stand-alone in a JAMMA outfitted cabinet..." That Tops adapter really makes me wonder how much draw of the 3.3v the Model3 takes... I...

    Sega Model2/3 - JAMMA Adapter Thread

    Alright, so I'm studying the only available Model3 to JAMMA adapter I can find, and unless someone else posts pics of another one, this is the only one i have for analysis. The JAMMA adapter itself only converts controls and RGBSG as well as a ground from the filter board to the JAMMA...

    The idea keeps crossing my mind but I can't really justify the design costs of a PCB that big, lol.

    Sega Model2/3 - JAMMA Adapter Thread

    With just the 25-pin header alone at a minimum quantity of 200 for $86+, that is way over my budget. I could make so many sets of JST-NH to Adam Tech cables with headers for that price. They do have all the headers though, but for those prices, it just inflates the cost per adapter so much...
