I think it will snap into the plastic ring, you don’t want to use glue because that will modify the weight/balance of the spindle At least if you buy from the Aliexpress seller you get 5 attempts at making it work

I was thinking you could just remove the metal ring that he needs from the PS1 spindle and put it on the Sega CD spindle instead

You can get them for a PS1 and they should still fit. Not sure if you’re affected by the tariffs yet but these still shouldn’t be too bad https://a.aliexpress.com/_mPlaT0R

Revision 1.1 is unfortunately not working having received and built the PCBs - please ignore this build for now, I will also remove it from the Github

New USB revision released - v1.1 - Updated resistor sizes for switch and button header - Added decoupling capacitor to 5V - Added resistors for LEDs to allow for smaller LEDs to be used - Realigned USB ports - Realigned screw holes Updated Gerbers available on Github now, BOM has not yet been...

The latest revision v1.01 boards arrived today and I put one together ready to install in its new home in my 4 slot cab I reworked the code to use only the bottom 4 connections and had some fun with the test LED colours Next step: installing in the cab

I have recently been working on a project and have got to a stage where I can release it https://www.arcade-projects.com/threads/released-open-source-neo-geo-mvs-marquee-driver.33135/ For those of you who have LAI MVS lowboys or MV4-U29 cabs without the backlit mini marquees this is for you I...

This is now released! PCB design files and Gerbers can be downloaded from GitHub - all functions except manual switching have been tested (waiting on boards with the switch to be able to test that functionality and will confirm once done)

Several people have requested the ability to run a panel in a cab where there may only be a single slot board due to failure of the 2/4/6 slot board. I have added 2 options for this Attract Mode Marquees will cycle through automatically on a 1 second delay Manual Mode Marquees can be changed...

The boards for the latest prototype revision arrived today - I am hoping this will be the final test version before production. This is the USB version designed for use with EL panels commonly found on Aliexpress All parts on the board are through hole and very easily available from Digikey and...

Yeah it’s not a bootleg where they use compatible parts to reproduce custom hardware like a traditional bootleg From what I’ve seen the PCBs on the reproductions are very well made and at least on par with original too

No it will work with legit PCBs. But due to the cost of originals, the risk of potential damage and the fact a bootleg exists so an original doesn’t need to be sacrificed the bootleg is recommended

Hello fellow A-P members. I have just ordered what I believe will be the final prototypes for a project I have been working on I recently bought an LAI (Australian manufactured) 4 slot MVS lowboy cab and discovered that these do not have the individual marquee lights, just a fluro to light up...

I recently repaired a 4 slot and installed a UniBIOS 4.0 and got the exact same error on boot I replaced the UniBIOS IC and it worked after that and thought it might have been dirty pins causing bad contact. Good to know this is a known issue on multi slot boards. I’ll send the owner a 3.2

That’s not entirely true. The internal connections can fail or the die itself could fail or be damaged CPS1 A and C customs are well known to fail sitting on a shelf

Yep could be that too. The black line is missing data. Don’t get your hopes up but it may be fixable

A broken PAL 1A usually causes the screen to turn into small squares but if it has fixed the issue for others, anything is possible I don’t think this is the case because the line is the same through all layers of graphics. I think the seller has tested it using another A board and has...

If the seller is saying the A board should be considered defective they may have already tested it? It could be a bad mask ROM but I wouldn’t buy a CPS1 set where the seller is saying the A board is bad

Great work on the repair! I believe this is the same audio module present on Snow Bros boards and it often fails there too An alternative option there is to populate the components directly on the board - if I’m not mistaken I can see the silkscreening on the board you have repaired here for...
