That is if the Series/1 had an operator panel, it was possible to run 
them without one, and then if the CE had to run diagnostics he would 
have to haul a panel and a diskette drive out with him.  They where a 
very reliable machine, but CEs mostly hated working on them since they 
rarely saw them enough to get really familiar with them, especially if 
they had 10SR disks those drives where bullet proof, the 62PC not so 
much.  I think they also used 62TM disks in Series/1 they where also a 
very reliable disk.
