One of my most indelible memories in software was running an .asm --> .com Z80 program after using sloooooow Basic. It was 100's, if not 1000's of times faster than Basic. I was shaking my head .... it can't be done already.
Also recall using the TI58 (amazing and really, really low level, but powerful). Maybe the HP41c? Or not?
And punch-cards on an IBM 7080 mainframe with an 029 keypunch in 1968.
Sigh. And sorry for the old war stories.
