The AT&T Globalyst 250 is a PC compatible laptop based on the intel 80486 and Intel Pentium processors (depending on submodel). It's actually a re-branded NEC Versa M/100 (250) or NEC Versa P/75 (250-P) model, sharing the same circuitry and features as those laptops, but with the AT&T/NCR 2-tone dark/light gray and turquoise color scheme. NEC made laptops for NCR/AT&T's higher end model lines up until 1996. Samsung made lower end models.

Technical Details

The specifications depended on the submodel of Globalyst 250 you purchased. There was a 486-based version, and then the 250-P shown here which was based on the NEC Versa P/75 model.

  • 486 DX4-100 (SL Standard) CPU (250), or Pentium 75MHz CPU (250-P, shown)
  • 8MB of RAM Standard expandable to 40MB with 4, 8, 12, 16, 32MB NEC Versa RAM Expansion Cards
  • Removable 1.44MB Floppy Drive that could be exchanged with a second battery for longer mobile uptime or other modules compatible with the NEC Versa M and P series laptops.
