My first machine was a PDP 11/45, which was installed at my fathers
place of work in the Southern General Hospital in Glasgow.
The Diagnostic Methodology Researtch Unit - they did early research in
computer assisted diagnosis of GI complaints, using a green CRT terminal
which asked the patient questions. Coded in Fortran (of course), and
they used Baysian statistics which in those days was pretty cutting edge
stuff.

I also remember programming on the HP 85 belonging to the Professor in
the unit http://www.hpmuseum.org/hp85.htm
