You have no idea what a long time ago is. I use to play artillery on my 50 KByte Tektronix 4051 computer, It accepted text Basic instructions. That was before the first PC. I thought I was lucky because I didn't have to use the old 4050 which I think had 25 KByte. Hot damn, the 4051 was the best in the world at that time. In college we designed and then built our own microprocessor using the latest FET technology. God, that was hard. Probably as difficult as building our own operating system in computer science
