I have two SF 354 drives and would like to upgrade one of them to a
double sidded drive. I tried to directely replace the drive mechanism with
a sony double sided mechanism. This didn't work. Does anyone out there
know how to upgrade one of these things, I know it can be done I have
seen direct replacements for sale in magazines.

I do know that there is one Sony drive that won't. I believe Jameco sells them for $59 or so. Depending on what mech you had in the drive before, it could be easy or hard. When I did the replacement on my old 354, it was a plug-n-play affair. Recently, I did another replacement on a friend's 354, and it was a nightmare. I guess Atari used different interface boards (those boards that have the Atari connectors on them) for different mechs. If you could tell us what mechs you have in those drives, it would be easier to diagnose the problem. One simple thing you might check is the drive ID jumper on the mech itself. Make sure it is on D0. You might also have to play with the other jumpers to get it working correctly.
