Using a Mac in 1987:
I was a university student, and had an assignment to analyze demographic data using a program called SPSS, which we configured using Fortran scripts. We could walk to the Math building and use a terminal to write run our batch jobs, which took about 15-20 minutes each time, then we’d collect the printouts.
But I had a Mac, and a modem! So I could dial in and run my batches from home using a terminal emulator.
The Mac OS didn’t have multitasking, but a beta program called Switcher was released which did let you load and switch between apps. If you didn’t save your work before switching, the computer would crash. And it crashed a lot! There was no memory protection, so apps could easily write into the memory of other apps.
So I’d start Switcher, load the terminal emulator, login and run a batch job. Then I’d start MS Word and a graphing program called Cricket Graph.
When the job finished, I printed the results to the screen, copied the table to the clipboard, and started a new batch. I pasted the table into Cricket, made a graph, and pasted the graph into Word.
Compared to today, it was very laborious. But at the time, it was very much state of the art, and I was able to write a paper with in-line graphs instead of an appendix full of tables. I don’t think I had a printer (they cost $500!!!) so I had to take the floppy disk to a lab to get a printout.
