IBM RISC System/6000 250

RISC System/6000, or RS/6000 for short, is a family of RISC and UNIX based servers, workstations and supercomputers made by IBM in the 1990s. The RS/6000 family replaced the IBM RT computer platform in February 1990 and was the first computer line to see the use of IBM's POWER and PowerPC based microprocessors. RS/6000 was renamed eServer pSeries in October 2000.

The RS/6000 250 was a workstation/server released by IBM in 1993.  In the sales manual for the system, IBM described it as follows.

'The IBM RS/6000 Model 250 is flexible and powerful, and performs well as either a graphics workstation or a server. Driven by a 66MHz PowerPC 601* microprocessor, it offers growth capability from 16MB up to 256MB of error checking and correction (ECC) memory, optional internal fixed disk up to 2GB, up to a maximum of seven SCSI devices on the SCSI bus, an optional 2.88MB diskette drive, an optional graphics adapter, and two 32-bit Micro Channel* card slots.'
