SPARCstation LX

The SPARCstation LX (Sun 4/30) is a workstation that was designed, manufactured, and sold by Sun Microsystems. Introduced in November 1992, it is based on the sun4m architecture and enclosed in a lunchbox chassis. It shares the code name Sunergy with the low-end range of SPARCclassic, SPARCclassic X, and SPARCstation ZX.

CPU support
The SPARCstation LX incorporates a single 50 MHz microSPARC processor.

Memory
The SPARCstation LX has three banks with two DSIMM slots each. The official maximum configuration uses 16MB modules, but the first bank can also hold 32MB modules giving a maximum of 128MB memory.

Disk drives
The SPARCstation LX can hold one internal 3.5-inch 50-pin, single ended, fast-narrow SCSI drive and a floppy drive. It also supports external SCSI devices. There is no IDE/ATAPI support.

Network support
The SPARCstation LX comes with an on-board AMD Lance Ethernet chipset providing 10BASE-T networking as standard and 10BASE2 and 10BASE5 via an AUI transceiver. The OpenBoot ROM is able to boot from network, using RARP and TFTP. Like all other SPARCstation systems, the SPARCstation LX holds system information such as MAC address and serial number in NVRAM. If the battery on this chip dies, then the system will not be able to boot, but it is possible to set a MAC address manually on each boot.

Dimensions
Its dimensions are 9.6 in x 10.4 in x 4.6 in (W x D x H). The weight is 11 lbs.

Operating systems
The following operating systems will run on a SPARCstation LX:
 * SunOS 4.1.3c onwards
 * Solaris 2.3 Edition II to Solaris 9
 * Linux - Some but not all distribution still support this sparc32 sub-architecture
 * NetBSD/sparc32
 * OpenBSD/sparc32

Differences between ZX and LX
The SPARCstation ZX is a SPARCstation LX with a Sun ZX "Leo" 24-bit color framebuffer.

Differences between Classic and LX
The SPARCstation LX has an accelerated CG6 framebuffer compared to the SPARCclassic's CG3. The LX also features 16-bit audio as opposed to 8-bit audio for the SPARCclassic. The motherboards of the two systems are otherwise similar, and both use the same chassis.
