Maple 4.2 (December 7, 1987)

notes
“Maple 4.2 goes cutting-edge on the Macintosh with a windows-based workspace you can scroll through to see past results, without losing them off the top of your screen. Other platforms have to wait a bit longer for this technology.”

“Maple V Release 2 introduced the "worksheet" interface which allowed users to combine text, graphics, and input/output, and for the first time, displayed mathematical output in textbook-standard notation. This "Classic" interface, which used only 1D Math, remained available in later versions (up to Maple 2021) as a legacy option.”
