The SPARCstation, SPARCserver and SPARCcenter product lines are a series of SPARC-based computer workstations and servers in desktop, desk side (pedestal) and rack-based form factor configurations, that were developed and sold by Sun Microsystems.
Thanks in part to the delay in the development of more modern processors from Motorola, the SPARCstation series was very successful across the entire industry.
Desktop and deskside SPARCstations and SPARCservers of the same model number were essentially identical systems, the only difference being that systems designated as servers were usually "headless" (that is, configured without a graphics card and monitor), and were sold with a "server" rather than a "desktop" OS license.
Most desktop SPARCstations and SPARCservers shipped in either "pizzabox" or "lunchbox" enclosures, a significant departure from earlier Sun and competing systems of the time.
These systems could accept one or two single or dual central processing units packaged in MBus modules.
