Anyone know if schematics are available for this, if so where?

Any info on it? Encrypted? Suicided?

Any info appreciated as I have a dead one here to fix.

Cheers,
Guddler.

There is a security chip on the board called the c-chip, not sure if it
relies on battery power, it handles sprites as far as i am aware

So it wouldn't be the culprit of a completely white screen on power up
then by the sounds of it? Guess I'll start with the usual CPU checking
etc...

RE: [ukvac] [Tech] Rainbow Islands
it's a 64 pin chip - has a label same as the eproms B22-xxx or B39-xxx
(depends whether its RI or RI-Extra) - it doesn;t suicide AFAIK (no battery)

if it's scrap - can I have the prom (I have a PCB with a dead prom!)
