Just "wasted" an hour this morning playing around with a OSS recreation of VisiCalc [0] This repo contained a link to the manual. Holy cow! [1] EDIT: This program is awesome. I was surprised and impressed by the screen splitting and whatnot. I'm paying off some debt, and I'll be using this program to track this now, unironically. From the introduction: > But the power of the VisiCalc program lies in the fact that the computer remembers the formulas and calculations you use while working through a problem. If you change a value on the worksheet, all related values change as the VisiCalc program recalculates the entire worksheet. > ... > Playing "what if" with the VisiCalc program is often a matter of changing a single value. If you enter a value at one location, you can copy it to any number of other positions. You can change, insert, delete, or move entire rows or columns. The worksheet is instantly restructured so that all relationships correspond to the changes. Doing the same thing with a calculator, pencil, and paper could take hours of erasing and recalculating . Very prescient. [0] https://github.com/geoffmoss0/VisiCalc https://github.com/geoffmoss0/VisiCalc [1] http://toastytech.com/manuals/VisiCalc%201.1.pdf http://toastytech.com/manuals/VisiCalc%201.1.pdf
