Thanks for all the valuable info. Does anyone have a take apart guide? One of the HD/FD caddies on the one with the Radius card, is popping out, thus won't let me shut the top. Both HDs spin up, but none of them show video to one of my old VGA CRTs with an adaptor. I tried both, and the Radius card on the one that has it.

The Ram Doublers are very strange! I wonder how much ram this machine has, the SIMMS are not labeled. Both have the Developers switches.

None of them Chime though.
