David Charles Robertson (that’s where the “DcR” comes from). After leaving university, I was fortunate enough to fulfil my lifelong dream of becoming a pilot joining the RAF in 1984.  For the next 13 years, I spent most of the time flying the Lockheed C-130 Hercules (left). I said, “Most of the time.”  I was selected to undertake a 3-year sojourn at the RAF College Cranwell training newly selected officer candidates.  My main tasks were to develop and deliver lesson plans in subjects ranging from Leadership to Oral and Written Communication.  I left the RAF in 2001 as a Squadron Leader.

Fulfilling another ambition immediately followed when I joined Cathay Pacific Airways Limited.  Starting on the freighter version of the Boeing 747 “Jumbo Jet,” I moved on to the passenger fleet in 2005 flying between destinations in Europe, the Middle East and the Far East.  I finally retired from aviation leaving at the beginning of 2011.

Back in 1995, we bought our first family PC: a Pentium 90 with a (then) whopping great 8 MB of RAM and a 512 MB hard drive running Windows for Workgroups 3.11.  It soon became apparent that our technical box of tricks was not as straightforward as PC companies would have us believe. For example, I was trying to play various DOS-based games but came across limitations with conventional memory - no, I didn't know what that was either.  This led to playing with config.sys (WHAT?!) and autoexec.bat, the latter which has nothing to do with vampires.

Later on, I then installed Windows 95 but my PC told me that I didn't have a CD-ROM.  I clearly did and tried to tell it so, but apparently I needed a driver, a concept I found strange as there wasn't a steering wheel fitted.

The best, though, was when I bought a modem which turned out to be faulty.  From knowing relatively nothing about a PC's internal workings, after 2 weeks I was ready to take a life!  "Hello? Helpline? Good.  OK, I've gone into the BIOS and disabled COM port 1 and tried installing it on virtual COM port 3 using IRQ 4.  What?  No, it still doesn't work!"

Over the last 15 years, I found myself enjoying building and fixing computers for friends and family on a regular basis, including an ex-colleague who called me “Doctor Computer” as I kept fixing his ancient Toshiba laptop each time we met.  I'd receive calls asking questions ranging from PCs slowing down through viruses to what sort of computer people should be buying.  At a somewhat of a career crossroads, I did some research into doing what I enjoyed as a hobby for a living, et voilá!  Now I’m a Sole Trader (nothing to do with fish) and running my own business.

So why choose me over another specialist?  I’m professionally qualified and CISCO-trained and CompTIA A+ qualified.  Personally, I'm quite outcome focused and of an age where integrity is more important than financial success.  I’m also resourceful and determined, enjoy puzzles and meeting people.  I'll always do my utmost to return a patient to you as I'd like it returned to me.


I've always enjoyed any training role I've had over the years.  It's wonderful when someone's eyes light up with the

realisation of knowledge understood. Moreover, as a Sole Trader (blah blah fish blah blah), my business depends not

only on my professional ability but on my personal qualities. Hopefully, I'm in a best position to offer you help and advice!
