I must have replaced thousands of those bloody Master keyswitches in my
time at an Acorn dealer.  Profitable though.  I formed the opinion that
machines coming in from areas of high levels of industry (and
corresponding air pollution) suffered more keyswitch failures, possibly
due to corrosion of the switch contacts.  Trying to clean the contacts
with e.g. switch cleaner was only ever a temporary fix and I
experimented with several type of cleaner.

We used to get in machines from schools in Runcorn and Widnes (an area
with heavy chemical industry) with multiple keyswitch failures.  If it
was air pollution causing the failures, what was it doing to the kids'
lungs?

The best M128 keyboard IMO is the Cherry membrane keyboard used in the
last production run.  That is lovely to type on.
