Restoring a VAXstation 3500

Hello everyone, Recently, I met up with listmember Rick Murphy to take a beautiful VAXstation 3500 (KA650, QBus, RX50, DEQNA)in BA123 enclosure, along with VR290 monitor, puck mouse and keyboard, off his hands. (Allow me to commend him for being a good sport, I was ~30 minutes late ;)) It is a near flawless machine, except both of its RD53s are dead as doornails. The platter isn't stuck, but the opening up the drive tricks have all been tried. It powers up and then powers right back down. (But is at least detected, it seems) In any case, I am looking to make this thing work again. :) I am looking for any kind of Qbus goodies, specifically a SCSI card. If this is too rare an item, I am looking for a DSSI card. If this isn't an option either, I am looking for any RDxx drive. I am also looking for an RX22 drive, so that I can load a kernel off it and not have to worry with all that stuff, just simple, reliable NFS. :) Lastly (and this is a long shot), does anyone have a spare backdoor to the BA123 enclosure, or even just the hinge would do (mine is falling off). Any replies are appreciated, I can't wait to get this thing up and running as a full-time server. :) -- Thanks, Torquil MacCorkle, III Lexington, Virginia
