The SPARCstation 1+: A Refinement of a Revolution
The SPARCstation 1+ (model Sun 4/65) is a Unix workstation released by Sun Microsystems in May 1990 as an update to the SPARCstation 1. It retained the compact "pizza box" enclosure of the earlier model, but upgraded the processor clock speed from 20 MHz to 25 MHz.
The system included expanded memory capacity and revisions to the system architecture. Like the original, it used SBus expansion slots to support hardware additions, including network cards and graphics accelerators. Sun targeted the machine at software developers, engineers, scientists, and academic institutions running the Solaris operating system. The 1+ provided higher processing speeds than its predecessor while continuing to sell at a lower price point than earlier high-end Unix systems. Units remain preserved as vintage computing items.
