Depends on the country. In the UK, the Amstrad 8256 and 8512 were very popular, and they were only launched in 1985. They were much cheaper than PCs of the time, and came with wordprocessor package and CP/M 3.0. We had about 25 of them in our lab, including one floating at 4000V in a perspex cage, used to control a C14 accelerator.

From memory, I used TP and them TM2 on CP/M to run an automated thermoluminescence rig, then FTL Modula 2. I wasn't very professional at the time, but then no-one was - most of us were working in isolation. Speaking from that perspective, I was not very impressed with Modula 2. The issue was not with the fundamentals, but the way that it was case sensitive and forced you to use caps for all the keywords, so that it was really annoying to type. As a lesser issue, the names used for type conversions between numeric types seemed to have no rationale, so they were easy to forget. I don't remember exceptions in TM2, and they would not have been part of the standard language. They appear to have come in with Modula-2+.
