This is a real silver lindbergh with a real version of Revision B (This is not a multi) that has been played in Japanese arcades and has tons of scores on it. Works great. Things that have been done:
Replaced battery on main board.
Replaced battery on JVS board.
Redid paste on Pentium 4.
Redid...
One of two things: Bad BGA or bad ram. To check if a BGA problem, push down on the BGAS one by one (big heatsinks) to see if it boots during pressure. If it's bad ram, it could either be the SH4 ram or the Holly ram
I left it on 3.17 cause I know different people want to do different things. Both work fine. One doesn't have a battery, but I'm sure if someone cared they would replace it anyway :P $225 shipped each in the US.
Works great. These are harder and harder to find since these require the prototype boards in order to make. $800 + shipping.
I will include the 4 roms needed for converting a deluxe into a F355 2 if you need them. (If you are converting a twin, you don't need it).
These are not from China (well they all originate from China lol), but from Japan. All have been tested and work great. $150 shipped each. I have 5 of em. All are 5.70 bios.
Ok so I have a problem here. I picked up 3 HUGE HUGE (emphasizing this) boxes of eproms in their own anti static boxes + plastic containers. They range from 27c256 (plcc and dip) to 27c4096 (dip) and everything in between. There are 1-4 in each, so it's random. There are both flash and eproms...
