I remember 8" and 16" discs, and also I remember a "computer" with a screen with the same screen layout as an A4, and the word-processing program in the BIOS..
Side note; I also remember writing ROMs by using ten switches. (one resetted the memory address-count, 8 contained the data you wanted to write, the last one wrote the data to the memory at the current address, and increased the address by one. (By using this I made a "intersection traffic light controller program" for two intersections which were in sequence (and buttons for crossings, and sensors for cars) as a project, which I later showed my teacher.. I kinda wish that I had built a "model" of the intersection and put the leds and sensors in.. but I was satisfied with just getting my light-scheme functioning okay and my project approved)
