The R2000 is a computer from the Digital Equipment Corporation (DEC) that was first released in 1984. It is a 32-bit mainframe computer powered by the DEC VAX architecture.
The R2000 features the traditional DEC I/O structure, which includes the UNIBUS and the QBUS. Like other DEC computers, the R2000 also includes the ability to use multiple operating systems, such as VMS and RSX-20/CTS. The R2000 is capable of supporting up to four CPUs and 16 cables for additional storage, making it a powerful and versatile server or workstation.
The R2000 also had various versions of CPUs, including the R2000 family, the R3000, R4000 and the R6000. The latter is the most powerful of the three and had multiple versions, including the R6000A, B and C, each with faster clock speeds and more advanced features than the predecessor.
The R2000 was a popular choice for many organizations during its time, and it was replaced by the R3000 which was introduced in 1989. Today, the R2000 is still used by many computer organizations as a reliable yet cost-effective computer.
