Ultra 1
From Wikipedia, the free encyclopedia
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 [1] and shipped with Solaris 2.5.
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. [2]
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 DIMM.
Similar Sun machines were the Netra i 1 servers which had the same chassis [3] and the UltraServer 1/Ultra Enterprise 1 servers[4].
