I started in the design and manufacture of computers back in the late 1950s, working on the Atlas and Orion machines in the UK. In the mid 1960s I moved to Canada and began designing systems that used computers. I also began to use computers during the design phase.
I well remember buying the HP 21MX series for some design activities. (It drove our IT people nuts. Computing was their business, I should get them to do all such work!) It had 8K of memory, later we had to increase it to 16K. We had 6 terminals, displays/keyboards. One of my people wrote the programs, including a word-processing program. It saved us over $100,000 on the project. I never again had a problem extending the use of computers in the design process.
In my time I have seen many changes, from transistors to the new micro-chips, and from programming in assembly language (using punched cards) through Fortran to all the new fangled software processes of today. Systems have changed from the size of huge buildings to the almost unimaginable small.
Unfortunately, since retiring about 15 years ago I have lost track of the new innovations. Hopefully bp will help me to alleviate this problem.
