The SPARCstation SLC: Integrated and Affordable

In May 1990, Sun Microsystems introduced the SPARCstation SLC (codenamed "Off-Campus" or Sun 4/20), a workstation that took a different approach to form factor compared to the "pizza box" and "lunchbox" designs. The SLC integrated the computer directly into the base of its monochrome monitor, creating a compact, all-in-one unit.
The SPARCstation SLC was powered by a 20 MHz Fujitsu MB86901A, LSI L64801, or LSI LSIS1C0007 SPARC processor, similar in performance to the original SPARCstation 1. This integration aimed to provide a more streamlined and potentially lower-cost solution for users who primarily needed a dedicated Unix terminal or a basic workstation for tasks like software development and text-based applications.
The integrated design meant the SLC had limited internal expansion compared to its separate-chassis counterparts, typically featuring fewer SBus slots. However, it still offered essential connectivity like Ethernet and serial ports. The monochrome monitor, while basic, was sharp and suitable for the text-heavy work common in Unix environments at the time.
The SPARCstation SLC was a popular choice for educational settings and businesses looking for cost-effective Unix desktops. Its all-in-one nature simplified deployment and reduced desktop clutter. Like other SPARCstations of this vintage, the NVRAM battery is a key component for continued operation today.
The SPARCstation SLC stands out in the SPARCstation family for its unique integrated form factor. It represented Sun's effort to cater to different market segments with tailored hardware designs, providing an affordable and convenient entry point into the world of Solaris and SPARC.
