I had hinted about making this topic a couple weeks ago in the welcome forum!
I got carried away with other stuff and projects and only today did I start digging in the pile of electronics to see if I can salvage something.
I have a little bit of experience fixing electronics and games but only fixed one arcade board before, a NBA Jam. Culprit was a broken trace.
I am not an expert and am self learned but I am normally aware enough to not make things worse.
I run my arcade games with a Supergun and can quickly test Jamma boards but I currently have no mean to use non Jamma games outside of ordering or building adapters for them.
So lets see what I have in this box! All are mystery boards but I think I identified a few! ( Click on the pictures to enlarge! )
Any repair help, tips, or information regarding the boards that are not identified is highly welcome!
Mystery board N.1Identification: Seta Aleck 64 Jamma board - Game most likely magical Tetris challenge!
Observation: Very dirty!! Two capacitors are missing on the right. Clearly ripped off, parts of the legs still showing. Mask rom on top left has rusty pins.
Plan: Replace the two caps and test. If non working, clean it and inspect further.
Mystery board N.2Identification: Unknown, has all the Looks of a Jamma bootleg
Observation: Very dirty!! The connector is in a sorry state and corroded, looks like it was sanded in the past. Has remnants of wires soldered to an expansion port, possible shorts there. Through hole components look flattened.
Plan: Clean the connector, remove old wires and inspect through hole components for detached connection, fix if any. Then Test.
Mystery board N.3Identification: Unknown Hai Wei board
Observation: Looks like all the roms were removed. Evidences of earlier repairs ( Reflowed ASIC ) Possibly more missing chips.
Plan: Nothing unless I can Identify it. With parts missing not much I can do.
Mystery board N.4Identification: Unknown Nichibutsu board.
Observation: Rather clean and no obvious Damage. I suspect this to be a non jamma board.
Plan: Identify it
Mystery board N.5Identification: Unknown Nichibutsu board.
Observation: Looks just like board 4 but has a battery, Rom numbers look like they follow from the first board. Quite intrigued by this pair. Rather clean and no obvious Damage.
Plan: Identify it
Mystery board N.6Identification: Data East board. Fighter's history Japan version.
Observation: Looks rather clean. No obvious damage.
Plan: Make a visual inspection then test.
Mystery board N.7Identification: Psikyo board. Sengoku Ace (J)
Observation: Looks rather clean but for traces of hand reflowing on the Processor. Possibly the most valuable board of the lot so making this one work would be great.
Plan: Make a visual inspection then test.
Mystery board N.8Identification: Unknown.
Observation: This little board is kind of cute. Does not look damaged but for a cap that is half thorn off. I do not think this is Jamma, does have a bootleg look to it.
Plan: Identify it, has the number AB-22B on it. No company name or anything. Does look kind of like a bootleg.
Mystery board N.9Identification: Psikyo board. Strikers 1945 (J)
Observation: Another cool Psikyo game. Quite dirty but not clear evidence of damage or earlier work done one the board. The big reservoir capacitor looks crusty, replacing it won't be a luxury.
Plan: Make a visual inspection then test. Replace capacitors.
