We had two teletype terminals set up in different rooms so those were our computer rooms. The terminals were connected by phone line to a mainframe at Xavier University in Cincinnati. The connection was pretty slow - probably 300bps or less. No monitors, just a printer and keyboard and an acoustic modem for each terminal. There were a few of us who learned a bit of some form of the BASIC programming language and we made some simple adventure games that basically provided choices that led to one or another result for each "step" of the "adventure". We also found ways to print out images using the typewriter keyboard characters. I thought it was pretty cool at the time and later on in the late 70s I went to school and learned a variety of programming languages such as Fortran, COBOL, some form of Assembler, and RPG (IBM). Then I got a job using computers and stayed with it until today. I'll be 73 next month.
