To this day I still haven't found out how to implement the Windows equivalent of del *.bak or similar when I need it!
I first discovered computers when during a very hot summer vacation. As a student I was working as a vacation trainee in a research station. They had just acquired an Elliot 903 and installed it in an air conditioned room. Thus I used every excuse I could find to spend time in said room! I learned a lot about paper tape readers & punches, machine code, and Elliot algol as well.
P.P.
