Hello Terry,
my name is Heiko Buss. I was a Field Engineer for the Century 100/200 and working for NCR Germany.
In 1972 i did the training for this machines in the ITEC in London at the North Circular Road.
I remember Tom Baldwin, Dudley Lowe, Dave Lewis and you.
A young men (Tom

??) driving a Triumph TR car teached us the 615-100 processor.
Another young collegue (I don't remember the Name) teached us the Tape Drives - it was his first time he did this.
Every Friday all the students where waiting in the Office of Mr. Fry (that's why this day was called the "Fryday"...

) to get their weekly expenses - very funny!
A older experienced men teached us the 615-200 processor. He came from Scotland and was not a member of the regular ITEC London staff.
One day we were waiting for you in the classroom to teach us the B1 Operating System. You came in and started immediately talking about the 626 Printer Controller (I remember the "trunk grabbing feature") and writing on the blackboard. We had to stop you and divert you to the B1 OS .....
This was the only lesson from you on this course.
I am still working in this job as a freelancer supporting small and mid-sized companys in PCs, Servers (Windows and Linux), Networking and programming applications.
But I very often think about the good exciting times with the Big Irons ...
All the best from Germany
Heiko
