I was in my late 20s when one of the trust managers at the bank I worked for brought in his Osborne. I was so very, very jealous. I'd just purchased the CP/M cartridge for my Commodore 64 and tried to convince him let me borrow the WordStar disk, but he wouldn't do it (and I really never went anywhere with CP/M on the C=64).
Coding on an Osbourne Executive.. portable yes, but the screen was so small, the external monitor was essential. Pick green or orange monitor phospher (very different looking). Big floppy disks and CP/M, Wordstar and .. Visi-Calc? Basic language.. authors workstation and could dial in with a modem to a BBS.
Looked like a neat little machine but (just a little) before my time, I’d have been in nursery when it released.
