Well then it looks like I'll keep my eye out for a TK50 and a mounting skid to restore this puppy into its normal state. Another observation is that the BA23 chassis has the connectors under the control box for an RDxx drive but there doesn't seem to be a controller in the uVax for them unless this controller was integrated into the CPU card or something? Its darn difficult to see where the cables come from and go to in the narrow tower, very unusual design it seems. --Chuck
