Hello Scott, broadly speaking of assembly...

     That explains the used drive I took home years ago that had no
     power plug (I found out later). I tried to make a power cable/socket
     for it but fried the drive anyway :-)
     BTW, everyone assumes the machine he wants to install a 5.25 disk on
     is not an XT :-)
     I suppose he will have to set dip switch(s) or jumper(s) if it is.
