I'll have to dig my "Project" out. It started off as a rusty "Junk treatment PANA Custom I picked up from YAJ for just 5200 YEN.
After a 60 day wait for it to arrive (Sea freight to the UK sucks) it turned out to be more of a shed than it looked in the auction - the video encoder board was missing, the PSU was blown and the rust was really bad.
So far I've taken it apart, stripped it back to bare metal, rust treated the shell and primed it to prevent any more rust before I get it put back together. Surprisingly all the buttons & sticks work fine with just two of the auto-fire switches needing replacement.
The plan is to repair the PSU (as it's an odd size) and install a GBS-8100 or GBS-8200 where the encoder PCB was so it'll do VGA out the back. I'll respray the case and if it still looks pants I'll fit a generic CPO over it before reassembling it.
I've got three PANA's a Boardmaster & a Sigma Rajin so have plenty of experience with these.
