You could feed that a 9v DC supply (check polarity) is it takes x6 AA's

That's a great idea, I see some folks have done this already (and also modded them with 9V batteries too)

Any of you guys have a suggestion for a cheap but decent crimping tool?

I need to crimp some 2.8mm spade connectors to a CPS2 kick harness.

I spashed out on one from AliExpress which should be arriving today, will see if its of any use. In the past I used pliers/solder, wasn't ideal. If you don't get a suggestion, I'll let you know how this one looks/work and pop up a link.

I always forget about Aliexpress for these things. Nabbed one using the old 'new customer' deal, apparently a 30 euro set for 8 euro. We shall see 😁

Only need it to crimp one end of 8 cables so if it works for that happy days!

Picked up the original type power supply for the Atomiswave cab.

AliExpress crimper is grand, it's no pro tool but for the limited cables I'm ever gonna make it's solid. Will replace that top AC connection, for now I can earth against any of the frame screws.

Online suggests these power supplies are the worst but with my existing cab and from testing this one, no issues (so far). No -5v rail but not planning on any old PCBs, it has a 12v 3.3v and oddly I thought, a 5.25v.

More power work planned, might need to make a Faraday cage for the stepdown transformer I've got planned, will see 🙂

I have a full size 2 player cabinet (fits 24inch monitor) that's free to a good home. It includes buttons, sticks, speakers and a few spare bits and pieces. It doesn't include monitor or computer or the marquee. It's currently disassembled.

I'll need it collected by the evening of the 14th, otherwise it's going in the skip!

I'm in Dublin 5. Let me know if interested.

The_B_Man · 13-07-2025 01:29PM

@Morpork I've sent a DM, in case nobody has offered to collect it. Would hate to see put in a skip.

Here's a blast from the past. Many moons ago, maybe up to 15 years, a certain nice poster here installed a load of battery holders into carts for me.

So long had passed, those batteries have started to die. But luckily all those years ago we future proofed for this very moment.

Good till 2040!

Edit - just tested it out. Few minutes of gaming to get a save in, turn it all off and set it aside for a few minutes.

Back in and...save is still there!

Over the weekend I went on a soldering spree - removed the generic arcade PSU someone installed and returned it to orignial Wei-Ya PSU'ness. Too an age but well worth it, cab back to near normal. From testing I already found that the slight interference of the monitor is gone! No need for a new stepdown transformer I thought I needed. 'Found' a cage that covers the PSU/power workings within - l̶o̶o̶k̶s̶ is all stock now.

Also picked up a '6 button' adapter (JAMMA connector passthrough) which has two displays for the 5V and 12V lines - not 100% needed…but sure :D

Picked up a instruction slip and a '100 Yen' sticker. Just the marquee light to sort out now but it is nearly there

o1s1n · 15-07-2025 09:05AM

That's really interesting about the lack of interference, did you recap the PSU too?

Where'd you get that six button jamma adapter? I see jamma+ is a thing on the new MiSTercade too, there's a switch on the jamma edge to enable it. (never really knew it was a thing!)

PSU - lesson learned, cheap/janky generic arcade PSU can cause interference. Didn't recap the new (to the cab) PSU. The existing ones look good and output voltages seem stable. Would need to test out an older board to confirm but so far OK. The monitor chassis was serviced since it was new, with little run time since so didn't think it was an issue with the monitor. Tbh, I thought I might need to change the stepdown transformer to a JPN 100V rather than US 120V to get rid of the interference.

6 button - came from eBay from a lad in France, I totally paid more than it was worth but not a lot of folks making these adapters anymore on forums and other sources had been either US or UK based…and ordered it before I found my new semi OK 'skill' at crimping connector pins.

The Atomiswave already has button 5 for both players going to the JAMMA connector (26+'d') which the MiSTercard and irkenlabs JAMMA Expander already support, but the 6th button is on a seperate connector. Those boards I think already expect that button 5 will be on the edge connector. I think if you flip the CHAMMA button (maybe labeled JAMMA+ on the MiSTercade?), it will also present button 6 on the edge connector…but I'm not 100% sure.

Second part, it adds the 'kick harness' which takes the extra buttons from the board (could be a SF2 board) and connects them directly to the edge connector and also the Atomiswave button 6 seperate connector.

End result - the cab support 6 buttons per player no matter what board is installed.

Was fiddling with a data east dark seal board last night.

It boots (or doesn't boot?) to garbled graphics and tiles. Sometimes in colour, sometimes in black and white, then just hangs.

Noticed that a socketed gal must have taken a knock at some point, chunk of the plastic gone at a corner, but it still appears to making physical connection.

The other problem, which I'd hope is the magic solution, is that I found a clean cut across 3 traces.

Otherwise the board is in very nice nick.

I think the fine soldering on the traces and the possible replacement of the gal socket is too much for me, so I'll stick it up for sale as a project if anyone fancies it
