I vaquely remember those. The first computer I ever used was with my older brother in the 70's...there was no  monitor, it was direct to printer spool. This was back in the era of tape drives and punch cards. He had an account at university comp lab, although he was in Jr High at the time. I think the first game I ever played was Zork...a text adventure game. Half the fun was trying to find the right verbage. I never really learned one till 97.
