This was my first computer, a Kaypro. My dad bought it for his publishing business to do payroll, but it was outdated by 1986. Cost $4k:
You could fold it up like a suitcase, so it was "portable"...
It used the nice big floppies, which were required for startup. You could switch disks once the computer had finished booting. There were a few interesting text role playing games, and one "action" game made entirely out of ascii characters, called "Ladder."
I used it all the way up until about 8th grade. My grandfather helped create one of the earliest versions of BASIC and taught me the elementaries of programming, on an Apple II, I believe it was. By the time Macintosh came around I knew how to use ResEdit to mod games (before it was even a term), to mess with my Dad while he was playing
Armor Alley.
Yeah, I had an Osborne, very similar, ran CP/M, not my first though
