Hi Darksoft, Just wondering if there's currently a waiting list for the F3 Multi V2, or if there are plans for another production run?

Great to see this come to fruition! Thanks to all involved. Please put me down for one @Darksoft

The test menu is accessed by pressing the test button, not by a dip switch.

Looks great. Well done! Are you planning on sharing the modified ROM's?

Hi all, I’m chasing some advice on a OutRun 2 SP setup running on Sega Chihiro hardware. The system will not retain the game assignment settings after a power cycle. Here’s what I’ve checked so far: The media board battery pack reads 7.5V with power off. The onboard CR2032 battery was...

That looks like Taito's Full Throttle / Top Speed to me.

No. This boardset is unique to Hang-On. Enduro Racer and Space Harrier are very similar, but definitely not compatible or convertable.

Hang-On uses normal Motorola 68000 CPU's (which you can see in the Op's photo), so there is no security or decryption of ROM's required.

Are you able to enter into the Diagnostic menu by pressing the Test button and then run a memory test? This era of Sega boards are littered with Fujitsu TTL IC's which are notorious for failing, so there's a high probability that one or many have gone bad and will need to be replaced.

Thanks for posting your repair log, geekmiki. My guess is that C430 (the blue tantalum capacitor) on the daughter board has gone bad.

According to your video, it's reporting that the 64Kb SRAM's are bad at G27, G28 and G8. You could try piggybacking them or use a logic probe to see if they've failed. The 052109 QFP SMD custom IC talks directly to G27 and G28 I believe, so that could have some loose pins or might have failed.

@bytestorm Were you ever able to get the 92631C-6 to act like a 90631C-5?

Was this ever done? Just seen it listed on the multi list https://www.arcade-projects.com/threads/complete-list-of-arcade-multis.20256/ however, the link doesn’t work and my Google searching finds nothing…

In that case perhaps you do have a failed TTL IC that interacts with the work RAM. Unfortunately the PCB schematics from Atari for Primal Rage are incomplete however, looking at the PCB layout I can see there are 74LS374’s and 74LS245’s at 20K, 20M and 22K, 22M which may interact with the work...

Hi guys. Just posting this here for a bit more visibility. As per link below. https://www.arcade-projects.com/threads/pre-sales-open-namco-system-1-multi-new-batch.27306/post-477334 TLDR - 14th spot in the queue for $400 instead of the normal $450.
