- SPARCstation 1
The SPARCstation 1, or Sun 4/60, is a
SPARC -basedcomputer workstation sold bySun Microsystems as the first of itsSPARCstation series. It was sold starting in April1989 , and the end of Sun's support for it was in1995 . It was designed for ease of production with heavy integration in a distinctive slim enclosure (a square 3 inch high "pizza box"). It was designed to compete with high-end PCs or Macs and sold for between US$8,995 (no hard disks) and around US$20,000. In the first year around 35,000 units were sold.The computer was based around a
LSI Logic RISC CPU running at 20 MHz, with aWeitek 3167 (or 3170) FPUcoprocessor . It was the fourth Sun computer (after the 4/260, 4/110 and 4/280) to use the SPARC architecture. It was the first of thesun4 c architecture. The motherboard offered threeSBus slots and had built-inAUI ethernet , 8 kHz audio, and a fast-narrow (4 MiB/s) SCSI bus. The basic display ran at 1152x900 in 256 colours, and monitors shipped with the computer were 16 to 19 inch greyscale or colour.Design
The SPARCstation 1 features several distinctive design and packaging elements driven internally by system designer
Andy Bechtolsheim and externally by design housefrogdesign . Bechtolsheim specified that the motherboard would be the size of a sheet of paper and the SBus expansion cards would be the size of index cards, resulting in an extremely compact footprint. The external design motif includes dot-patterned cooling vents on the side which are echoed by a "dimple" pattern on the front face, and "Sun purple" feet.Memory
The SPARCstation 1 takes 30 pin
SIMM s in groups of four. It can take either 1 MB or 4 MB SIMMs as long as the size is consistent within a bank. There are a total of four memory banks, which can give a total of 64 MB of memory. The memory bank nearest the floppy disk drive should be filled first. If not, the OpenBootfirmware will hang while memory checking.Disk drives
The SPARCstation 1 has space for up to two hard drives and one floppy drive internally. The machine will take any 50 pin
SCSI -2 hard drive, but the OpenBoot BIOS will not boot from any partition which starts or ends after 1024 MB.The floppy drive, like the Macintosh's, is unusual in that it has an electromechanical eject mechanism rather than the conventional eject button, and therefore must be ejected by the operating system or OpenBoot. The machine can connect to anySCSI CD drive, via either theSCSI connector on the back or by connecting it to any spare internal SCSI connector via a 50 pin cable.NVRAM
The SPARCstation 1 uses an M48T02 battery-backed RTC with RAM chip which handles the real time clock and boot parameter storage. The only problem with this chip is that the battery is internal, which means the entire chip must be replaced when its battery runs out. As all SPARCstation 1s made are now older than the battery life of this chip, a substantial number of these systems now refuse to boot.
Operating systems
The SPARCstation 1, 1+, IPC and SLC can run the following operating systems:
SunOS 4.0.3c through 5.7 (Solaris 7)Linux (Modern versions may have trouble with the limited amount of memory in these machines)NetBSD 1.0 onwardsOpenBSD - All versions.Related computers
The SPARCstation 1+ (Sun 4/65) pushed the CPU to a 25 MHz LSI L64801, upgraded the coprocessor to a Weitek 3172 and installed a new SCSI controller.
The
SPARCstation IPC (Sun 4/40) is a version of the SPARCstation 1+ in a lunchbox style case and onboard video.The
SPARCstation SLC (Sun 4/20) is a version of the SPARCstation 1+ built into a monitor cabinet.The
SPARCstation 2 (Sun 4/75) is the machine's successor and was released in 1990.External links
