My vote is on number 3. If pressed, I would look for a dead short in the 850 somewhere that killed both power supplies. (I'm guessing that Atari didn't protect either transformer via fuse - after all, sealed units never need service, right?) Maybe there's a fuse blown in the 850, but this is unlikely - if it doesn't protect the transformer, it's not doing much. As far as replacement goodies, I'm not sure - BRE's catalog had some 8-bit hardware stuff last I saw, but I haven't looked at a recent one. Are there no 8-bit magazines left for suppliers to advertise in? Good luck! Max J.
