The SPARCstation 1 (Sun 4/60, code-named Campus) is the first of the SPARCstation series of SPARC-based computer workstations sold by Sun Microsystems. The design originated in 1987 by a Sun spin-off company, UniSun, which was soon re-acquired.^[1] The SPARCstation 1 has a distinctive slim enclosure (a square 3-inch-high "pizza box") and was first sold in April 1989, with Sun's support ending in 1995.

Based on an LSI Logic RISC CPU running at 20 MHz, with a Weitek 3170 (or 3172) FPU coprocessor, it was the fourth Sun computer (after the 4/260, 4/110 and 4/280) to use the SPARC architecture and the first of the sun4c architecture. The motherboard has three SBus slots, built-in AUI Ethernet, 8 kHz audio, and a 5 MB/s SCSI-1 bus. The basic display runs at 1152 × 900 in 256 colours, and monitors shipped with the computer were 16 to 19 inch greyscale or colour.

Designed for ease of production to compete with high-end PCs or Macs, its principal competitors were the IBM PS/2 Model 80, the NeXT Computer, and Sun's own 3/80.^[2] It sold for between about US$9,000 (equivalent to $22,100 in 2023) with no hard disks, to US$20,000 — and in the first year around 35,000 units were sold.^{[citation needed]}
