bump

I had a bare parts CPS3 board that looked very fixable so I ended up fixing it. The board is washed all customs I reflowed and tested for hours, new cart slot I will link the repair thread. I would say 550 shipped since it's a bare board with no simms...

all good thanks.

Happy to do it even though it was a pain in the ass, was a challenge to get this thing from what it was to working order. I also learned a lot in the process so I am sure the next one I will know what to look for.

any trades?

A buddy gave me a parts CPS3 he had, it was already missing the 60 MHz oscillator, the 1D character ram, and had trace damage from the oscillator removal. I replaced the 60 Mhz crystal, the 2D character ram, fixed the trace damage only to find it having Character ram error. I reflowed the ppu...

take that shit off its only used for red earth and if it blows up it's a bad thing, trust me I had to fix some with this thing blown up.

OK the game finish writing and is running perfectly. https://x.com/Cruzlink2/status/1947788093681242483

Well @cmv040 wanted to make this board into a multi down the line. I told him I had the extra 128mb he would need and could convert his cart. Just burned the CD and converted the cart writing 3S right now and so far so good.

Nevermind guys I spoke to furtekk he said we would need a cpld to do it. To grab the original clock and divide it as the PPU originally did without loosing sync of the data stream.

I am thinking the same thing but using a 14.318mhz and effectively put it in the path of pin 91 to replace it as the dac clock. Do you think that's doable? https://www.digikey.com/en/products/detail/vishay-dale/XT9MNLANA14M31818/24629604

@TheCrow I still have the old PPU and it's a shame, I have another board with a dead PPU. would I be able to drive the sound DAC with a separate crystal? Like put it in the same path as ppu pin 91...

thanks bro but I honestly think I am just a stubborn fuck that don't give up. once I am invested in a repair it's hard for me to stop.

This board did not wanna go off peacefully lol. I turn it off after hours of testing last night to clean off all the flux off it, turn it back on this morning and it's missing simm 6. I took off the simm and started testing connections on the 3383 buffers, found that leg 13 which is common to...

shhhhhhhhhh
