I've never used Turbo Pascal, but I've used UCSD Pascal, which was also pretty small. In a college computer graphics course in around 1980, we ran UCSD Pascal on Terak 8510/a machines, which had a total of 28K 16-bit words (56K bytes) of RAM. The Terak was an interesting machine: > The Terak 8510/a of 1976 or 1977 was among the first desktop personal computers with a bitmap graphics display. It was a desktop workstation with an LSI-11 compatible processor, a graphical framebuffer, and a text mode with downloadable fonts. Despite the lack of a MMU, it was capable of running a stripped version of UNIX version 6. It was the first personal machine on which the UCSD p-System was widely used.[1] Various universities in the USA used it in the late 1970s and early 1980s to teach Pascal programming. It provided immediate graphic feedback from simple programs encouraging students to learn.[1] Also, in those days, we were running Version 7 Unix on a PDP 11/45, which supported several concurrent users in what would now be an unimaginably tiny 256K of RAM.
