So my friend and I picked up a SEGA Turbo mini lastnight from a local guy who said that it worked at the place he bought it from but it was broke when he got it home.
Took the back cover off to find a master lock, a pencil, a tv antenna and a piece of a slot car track stuffed in the already small confines of the cab.
Still doing a little R&D on the cab but the machine just makes all sorts of crazy sounds when it's turned on. But every 1/20th of a power up it starts up fine for a little while then it goes bonkers again. I was able to get the tests working and everything passed, ROM and RAM then it seized up on the input tests and went crazy again.
I'm thinking it could be a power supply issue, as someone put in a switcher alongside the other PSU in the cab, which leaves little room. I swapped the switcher for a new one and I also pulled the board and reseated all the chips as well and it continues to go haywire.
Does anyone repair these things and would other boards be compatible with the mini if I need to replace my boards?
