The patriarchy is the reason you know the names Steve Jobs, Bill Gates, and Elon Musk, but you've never even once heard the name Evelyn Berezin.
Tom@LadyDragonfly Was Berezinโs Data Secretary a word processor in ways that the IBM MT/ST was not?
@LadyDragonfly @LadyDragonfly I wrote a reply to your Selectric response, but it looks like that's gone now, so trying again. It's hard to find much information on the Data Secretary, but it looks like its feature set was similar to the MT/ST's. If anybody knows about its specific features or has a manual, I'd really like to hear.
"Its feature set was similar"
No.

@[email protected] @[email protected] @[email protected] My dude. The history here is complex and nuanced, as real history often is. Iโve talked to the engineers who built the first commercial word processor at IBM. I spent a week in the archives at Microsoft. I interviewed Evelyn Berezin before her death. I then literally wrote the book on this. You are well out of your depth. https://www.hup.harvard.edu/catalog.php?isbn=9780674417076
@LadyDragonfly @mkirschenbaum Can you share a little about the feature differences between the MT/ST and the Data Secretary?
@tom @mkirschenbaum I would direct you to ask your question of the book's author. Or, read the book for your answer.
