Used: (1988) Zenith 250 desktop. No internal hard drive (dual floppy disks), orange monochrome display, and encased in a metal box to process classified data (it was a Tempest thing).
Owned: (1992) Gateway Nomad(?) laptop. 4mb RAM, 78mb hard drive, and 64 shades of grey display. I still had it up until 2020 when I cleaned out my man cave.
