Wouldn't mind a copy of the schematic, assuming it hasn't been uploaded
to somewhere already.

(Does anyone know if schematics for the Master Turbo's coprocessor exist
anywhere by the way?)

I could probably scan mine and email you the scans sometime (seriously,
I find dumping boards on the scanner works quite well for
reverse-engineering stuff)

I really need to dismantle it and get some photos sometime anyway.

Dry joints seem to be the most likely problems with the players - the
solder quality's awful. I've seen two different releases of the player;
one has lots of extra components bodged onto the underside of boards
etc. (but both still suffer from poor quality)

I'll try and get the service manual scanned sometime soon...

Oh, and do be aware that the players only do the video overlay on the
RGB output and not the CVBS output - that's caught me out in the past.
:-)
