>So, here's a thought for ya: MS Excel from back then won't run on anymore

Here's a thought for you: it actually does run on Windows 10.

In particular, Excel 3 for Windows 3 installs and runs on Windows 10 out of the box. Here's a screenshot on my system[1]

Again, let me emphasize: this is software with a GUI written in 1991 for an OS released in 1990 which just works on Windows 10 in 2018 -- no VM required.

This is the second major release of MSOffice for the PC. The previous release, Excel 2, was running under Windows 2.0, which nobody wants to remember, and which is indeed not supported.

On the other hand, its installer - a DOS program - runs fine because DOS programs still run in windows 10.

The compatibility breaks on 64-bit releases of Windows. But all the major versions are available in 32-bit, which you can run on any hardware you can put the 64-bit version on.
