Description

The Sun 3/80 was the desktop model of Sun's last Motorola 68k based product line (sun3x architecture with Motorola 68030). It was developed as a continuation of previous desktop machines concurrently with the SPARCstation 1 (sun4c architecture with SPARC processor) which aimed to bring the new RISC technology to the desktop. Mechanically similar, the Sun 3/80 was between four and ten times slower but still sold for 2/3 the price when both machines were introduced in 1989. The SPARCstation 1 was a great success and ended the use of Motorola 68k processors for Sun's desktop machines. CPU is 68020-based. 68881 math coprocessor; 8255 x 1; Z8530 x 2. Board includes built-in Ethernet controller, video, keyboard and mouse controllers, two serial ports. 3 x DIN connectors for connection to backplane.
