I also maintain a decades-old Macintosh that is kept simply for offline tax / accounting / business invoicing (USB print).
Even as a Millenial, it is extremely frustrating that modern versions of Excel/Office/&c are always trying to be so [un]helpful... auto-dates/-formatting is just such an absolute nuissance.
The day this machine dies will be one of great personal mourning / frustration.
Actually I almost never use a GUI word processor, just a lot of markdown/asciidoc or simply plain text. I do use Google sheets a lot for all kinds of stupid little things -- just so convenient that it's all automatically on every computer/phone/tablet I own -- or anyone else's computer I have access to, and I can share reader or editor links with people etc.

Thanks for the emulation alternative, OP!
