HP-1000

The HP 2100 was a series of minicomputers produced by Hewlett-Packard (HP) from the mid-1960s to early 1990s. The 2100 was also a specific model in this series. The series was renamed HP 1000 by the 1970s and sold as real-time computers, complementing the more complex IT-oriented HP 3000, and would be the starting point for a line of desktop computers. They would eventually be phased out in favor of UNIX-based RISC workstations.
