After a year of it being unused, i realised my Harley Davidson 3D was totally gone. Its not the weired glitches, i have a black screen with only 2D graphics. I got everything out of the cage and sprayed contacts with KF contact but nothing better. Ideas before i swap the 3d board with a...

Whoa you have spoted an official crimp guru! Only now i know crimp geeks exist Thanks for the ressource though:thumbup:

Dear all, I'm looking for alterantive to expensive NOS seat rails for model 2: Daytona USA (6011-7493 and 6011-7494) and model 3: sega rally (Sega 601-9060-91) I can do slight modifications by drilling holes if needed. Thanks for inputs Dav

Thank you so much for the infos. will get the F crimp first since its most of my intended use. cheers D

Hello, Can you help me select an affordable crimp tool that would deal with the most commons pins: JST-NH / AMP-UP / Molex eventually DuPont Thanks

my understand is that step 1 and 1.5 can be considered as original Model 3 (though specs are different... )

Thanks, so accoring to the mame driver: 837-11858 MODEL3 CPU BOARD 837-11859 MODEL3 VIDEO BOARD 837-12874 MODEL3 STEP 1.5 CPU BOARD 837-12875 MODEL3 STEP 1.5 VIDEO BOARD it gives me a good starting point but if some1 can confirm by eye, it would be awsome :thumbsup: @stj how is it contradictory?

Dear all, I need info on the CPU and GPU boards of these two revisions please. The info available on segaretro is scarce regarding model numbers. If you have pictures of which is which it would help aswell. Thanks by advance best. D.

Epilogue: The HOT was legit so had to look else where After checking all plastic and chemical capacitors, diodes and resistors, (even the mosfet Q404) around HOT in the hunt for the short, i found C416 being bad and c471 low. i've also read that horizontal coil on the yoke, if shorted could...

Q412 was fried as well, using the bulb between colector and ground worked Latest verdict: new fake HOT or short downstream

Update: Q412 was changed for a new, just in case. D402 was good R456 open D401 was shorted on the right diode (between Q412 Col and D401 anode) after changing D401 and R456, power-on instantly blew R456 Verdict: something short in the horizontal deflection circuit

Dear All, i swapped q801 with a "probably working" one and had a few voltages at chasis power supply secondary but under working specifications TP1 (C831) 163.8v - 180v expected TP2 (C833) 103v - 112v expected TP3 (C834) 163.8v - 180v expected TP4 (C835) 19.2v - 29v expected TP5 (C836) 4.9v - 7v...

Hello, I bet he speaks english use the online form: https://www.rep-arcade.com/contact In theory you could pretty much hook up anything in a cab but it will need rewiring but force feedback needs specialized pieces of hardware the curent best option that combines any original SEGA FFB hardware...

dear @Mukuro_W how do you get the rev of 29e31s PCBs?

Merry Xmas Arcade enthousiasts! i resurected a quite old 29E31s (according to dust accumulated on the PCB) by swapping the existing cliking Flyback with a previously known working one. image was a bit blurry though compared to other similar chassis and focus wouldnt help. after a few days of a...
