All spreadsheets used to run in your terminal, in the old days. You can still download one here and I wouldn't be surprised if it still works: https://winworldpc.com/product/quattro-pro/4x

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?

Yes! My first encounter with spreadsheets was SuperCalc for CP/M, and I suppose you would call it a "TUI" nowadays.

there are some videos about quattro in those days and i was sincerely surprised how featured and advanced it was

the ratio of space / cpu / capabilities (beside the network part) is something that reaches deep in my brain

Right? Visicalc wasn't using anything that a terminal didn't offer.
