My first exposure to computers was back in university when I had to write a FORTRAN program to analyze some statistics that where provided by the teacher.
It had to be documented then the code transfered to 80 column punch cards then submitted through a glass framed window then we had to wait overnight to receive the output in a communal drop box.
It was quite fun at the time.
I graduated and was hired by IBM Canada in May '67 and worked for them for 31 years and had many great experiences meeting many people from around the world and savoring many different foods.
My first exposure to Personal Computers ( PC ) was back when IBM introduced their PC back in '82 because I was in the Canadian Hardware Support center where we had to provide support to the field service personnel to help them fix problems with them if they arose for their customers.
I became involved in the telecommunications area of PC communications as my background in large host based telecommunications helped.
We started out with 300 BAUD

modems but were pleasently surprised when 1200BPS modems came out.
