You can run Lotus 1-2-3 for Unix in modern Linux : https://github.com/taviso/123elf

Lotus 1-2-3 was the first spreadsheet I ever used around age 9 so this is really bringing me back!

I am shy to admit I used visicalc on an HP-85.....1980 ?¿? maybe...I learned the periodic table with a basic program I made on that piece of art.

What a great name :) ("elf" = 11 in German)

what's the relevance of 11 in this context?
