The Ultra 1 was available in a variety of specifications. The Ultra 1 Creator3D 170E launched with a list price of US$27,995 (equivalent to $56,000 in 2023) - along with the Ultra 1 Model 140, and Ultra 1 Creator 170E.[1]
CPU
Three different CPU speeds were available: 143 MHz (Model 140), 167 MHz (Model 170) and 200 MHz (Model 200).
Models
Model numbers with an E suffix (Sun service code A12, code-named Electron) had two instead of three SBus slots, and added a UPA slot to allow the use of an optional Creatorframebuffer. 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, code-named Neutron).
Memory
The Ultra 1 uses 200-pin 5V ECC 60 ns SIMMs in pairs, the same memory used in the SPARCstation 20.
Similar Machines
Similar Sun machines were the Netra i 1 servers which had the same chassis [1] and the UltraServer 1/Ultra Enterprise 1 servers [2].
