@johnmacintosh This reminds me of the #TI990/4 system we had in school. I learned #Pascal on it. We had a 10 MB hard drive and another 10 MB removable hard drive, both being 16” drives. There were 6 terminals as shown below.

The whole system had 384 KB RAM, which results in 64 KB RAM assigned to each terminal for running a program.

The #TexasInstruments implementation of #Pascal was highly unreliable, so we had to use #UCSD Pascal, IIRC.

Those were the days! 🤣
