Fortunately, my mom worked in the scientific research institute - because in time of my childhood, there were no computers for private use... 
I wrote my first program in some sort of BASIC, on soviet ECM (stand for "Electronic Calculating Machine" - there was no capitalistic word "computer" that time  ) "Iskra-226" (stand for "Spark-226")... That monsters had 64Kb RAM and separate floppy drive unit, big as whole modern computer (I can't remember exact size of diskettes but they were MUCH larger than 5 inches...) The computer itself was a big black box with small built-in monitor with screen resolution 512x256x1 and 80x25 text (overlapped with graphics, by the way - compare this with IBM PC's CGA and its separate graphics and text modes headache!)
