  • 1985

This early portable computer weighed an incredible 13.6 kg and thus, had a handle so that it could even be carried around. It is IBM’s response to a very successful portable machine by Compaq and even has a lower price tag. Similarly to other early computers for the mass market, it had no hard drive but two floppy disk drives. Notably, there were several problem-solver libraries available for this machine with routines for math, statistics and finance.

CPU: Intel 8088 @ 4.77 MHz
Memory: 256 KB RAM
Operation system: PC-DOS v1.0
Harddrives: 2 × half-height 5.25"" 360K floppy disk drives
