That plainly sucks. I wonder if these hr flybacks are that bad, even for MS8 or MS9 chasis,

I'd be quite interested in knowing how it goes with the new flyback. I may need to change one and want to know the quality before either ordering a replacement flyback or getting a new chassig and using the other for parts.

Hello, Recently, got a MS9-29A fully recapped. Today, I noriced the image starts to shake and "collapsing" at some moments. Does anybody else has experienced this issue? What would you suggest me to start checking, bsides cold solder joint. Thanks!

this is really cool!!

would you eventually sell repros of these labels?

Alredy tried, no luck. I'm starting to believe the former owner replaced the original B board for an older one. I'm looking for a Rev 7 B board to give a try.

Looking for one to repair a 19xx game. Thanks!

Checked all mask EPROMs, zero issues, so I started to check schematics online to trace the 2 pins the 4MBit EPROMs are not using. GFX Address A20 is not available when using these 40 pin mask EPROMs. Same with gfx address A21 By tracking the traces, indeed, this address is not available...

LOL, true. I'll try with another B board, just in case. I still have to check the 32 mbit eproms. So far, no issues.

Nope. Exactly the same.

Had the same issue! Try SOOS-SO-0SS0SO-OSSOOSSO-OSSOOSSO That brought the game back to life.

Ignore how messy it looks… I ran out of whick. Tester shows as following for the gfx area : SOSOSO - SOSOSO.

Yes, it’s using an E PAL and there is no issue with the sound. Attached a link to a video of how it looks right now. https://www.instagram.com/tv/CURnVs-gYzN/?utm_medium=copy_link https://www.instagram.com/tv/CURnVs-gYzN/?utm_medium=copy_link

The pcb with 40 pin, 512KB eproms installed where I’ve always seen 42 pin eproms.

This one came with a E PAL. According to the spreadsheet I've seen online, it should be a F PAL. Took the PAL from a MSH and things got worse, as there were jailbars and the sound was messed up.
