The Ultra 1 is a family of Sun Microsystems 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 and shipped with Solaris 2.5. It is capable of running other operating systems such as 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 Ultra 1 Creator3D 170E launched in November 1995 with a list price of US$27,995.

Our model is the 167MHz SErvice Code A12-170
Part Number 600-3809-02
Serial Number 612F1521

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.
