Ultra 1

Ultra 1

The Ultra 1 is a family of Sun Microsystems computer workstations based on the 64-bit UltraSPARC microprocessor. It was the first model in the Sun Ultra series of Sun computers, which succeeded the SPARCstation series. It launched in 1995 [http://www.sun.com/smi/Press/sunflash/1995-11/sunflash.951107.19754.xml] and shipped with Solaris 2.5. It is capable of running other operating systems like Linux and BSD.

The Ultra 1 was available in a variety of different specifications. Three different CPU speeds were available - 143 MHz (Model 140), 167 MHz (Model 170) and 200 MHz (Model 200). The Model 200 launched in August 1996 with a list price of US$27,000 for the Ultra 1 Model 200E. [http://www.sun.com/smi/Press/sunflash/1996-07/sunflash.960723.22454.xml]

Model numbers with an "E" suffix (Sun service code A12, internal codename "Electron") had two instead of three SBus slots, and added a UPA slot to allow the use of an optional Creator framebuffer. In addition, the E models had Wide SCSI and Fast Ethernet interfaces, in place of the narrow SCSI and 10Base-T Ethernet of the standard Ultra 1 (service code A11, codename "Neutron").

Ultra 1 uses 200-pin 5V ECC 60ns SIMM.

Similar Sun machines were the Netra i 1 servers which had the same chassis [http://sunsolve.sun.com/handbook_pub/Systems/Ultra_1E/Ultra_1_140E_170E_200E.html] and the UltraServer 1/Ultra Enterprise 1 servers [http://sunsolve.sun.com/search/document.do?assetkey=1-25-19521-1] .
