Lotus 1-2-3 on the PC w/DOS VisiCalc started it, but 1-2-3 finished it. "It" being the discussion of what a spreadsheet can be, and also VisiCalc itself.

🪨 Lotus 1-2-3 on the PC w/ #DOS 🛠️

Did you know #Lotus123 is still referenced in #Excel documentation, but not #VisiCalc? I spent time getting to know #VisiCalc's killer. When I struggled to make a chart, I called on the help of #AI. AI from 1986!

New post just went live. I examine the first #spreadsheet, #VisiCalc, and learn a lesson about the benefits of mundanity in software. Guest appearance by your favorite grain: sorghum! #retrocomputing

VisiCalc on the Apple II In 1978, Dan Bricklin and Bob Frankston took out a loan to fund development of "Calcu-ledger," the very tool that could project if taking out a loan were fiscally prudent. In 2025, VisiCalc still has ...

Happy #SpreadsheetDay! This time, I examine how much DNA from the first spreadsheet remains in today's software by calculating protein levels of ration formulation for swine, as you do.

Not the sliced Apple, the shorts on the biker girl and the production maidens (center).

Apparently #Visicalc for the #Commodore #PET relied on a ROM chip, really as more of an anti-piracy dongle. Since the C64 is like a PET with extras, it's shocking no #demoscene coder has cracked it to run on a #C64 by now. Would be quite a way to cement oneself in history as elite. Also #tits in adv

A vedere la data, sembra siano passati solo 40 anni 😉. L'ho scritto per un amico, che si era innamorato del #Visicalc, ed aveva uno dei primi #C64.
Bei ricordi, di quando per programmare in modo efficiente (e non solo in basic) risparmiavi anche pochi #byte.

Software Arts fue una compañía de software fundada por Dan Bricklin y Bob Frankston en 1979 para desarrollar VisiCalc, que fue publicada por una compañía separada, Personal Software Inc., más tarde llamada VisiCorp. Lotus Software la compraría en 1985.
