Ah, brings back memories of being a Silicon Graphics Customer Support Engineer based in London and the Home Counties, back in the late 90's and early 2000's.

Indy, Indigo, then later the Octanes, and others I can't quite remember the name of off-hand.

The video post-production companies in SOHO - I saw the CGI being rendered for Event Horizon...

The "IBM Stiction Problem" as it was called. Batches of IBM hard drives that worked fine for months - right up until the machines were powered off - which then entailed an on-site visit. The stifled gasp from the customer as I remove the old drive and give it a stern tap on the desk, to get it unstuck so I could clone it to the replacement. ;)

Enjoyed that job immensely, except for the driving around London bit.
