Ken,
This discussion does my geezer's heart good.
I used to maintain Honeywell mainframes in the late 1970s, some of which had
core memories. Tapping them on the floor wasn't an option since they were such
huge beasties but they did have space for spare bits. I've swapped to the
spare bits o

I can't say I blame them. It was a lot of work to get a drive running after a
head crash. If it was a bad crash, there could be extensive cleaning to be
done followed by replacing one or more heads. Then the new heads had to be
aligned. If you hadn't cleaned thoroughly enough, you risked dam
35 years ago I got tasked to write a simple expert system in Turbo Prolog
because I was familiar with Turbo Pascal. The goal was an application to
assist new members of the help desk. I have vague recollections of having to
define rules to evaluate answers to simple questions. What I remember
I found Tim Peterson's old blog a while back which contained some interesting
tidbits about the history of DOS from the original author.

I think IBM always called their service techs CEs, didn't they? Honeywell and
at least one small company (Atex) which serviced DEC PDP-11 machines called the
same position a Field Engineer.
One site I used to service (USGS in Reston, VA) had a split computer room. The
left side was for IBM ge
