I understand that the Sears stores in the US replaced their Series/1
machines with a 9371, Sears Canada replaced theirs with a small AIX
system as did the late Eatons Dept store. State Farm Insurance agents
used to have Series/1 machines in their offices, they too replaced them
with 9271s. The machines in the Sears stores stores did not have the
operator panel, nor did they have a diskette drive so if you wanted to
run diagnostics on them you had to haul these items packaged as a CE
tool to the site with you. The biggest problem with servicing Series/1
was they where so reliable that unless you where maintaining a lot of
them you never got good at them.
The channel adapter on the Series/1 had a rather large flaw, if you did
not disable the interface before shutting down the Series/1 it would
upset the channel it was attached to causing a flurry of channel checks
that could bring the host system to its knees. When I worked in the IBM
Toronto Lab we had two channel attached Series/1 machines with 72MD
diskette units that we used to create diskettes from images sent to us
and also to send diskette images. These Series/1s pretended to be a
3270 control unit so that the MVS host system knew how to talk to them.
