SPARCstation IPX
The SPARCstation IPX (Sun 4/50, code-named ''Hobbes'') is a workstation that was sold by Sun Microsystems, introduced July 1991. It is based on the sun4c architecture, and is enclosed in a lunchbox chassis. Specifications CPU support The SPARCstation IPX incorporates a 40 MHz Fujitsu MB86903 or Weitek W8701 processor. Weitek sold an 80 MHz aftermarket "SPARC POWER μP" (2000A-080 GCD) processor for the IPX, which requires a ROM update to v2.9. Memory The SPARCstation IPX has four 72-pin SIMM slots for memory expansion. The memory uses parity Fast Page Memory (FPM) SIMM's with speeds of 50-80 ns. Slots can be filled individually giving a maximum of 64 MB memory. Paired memory modules decrease access times via "bank interleaving" resulting in faster memory and overall system performance. Additional 32 and 64 MB SBus "Above Board" RAM expanders will fit and work with the IPX using the 8-pin J101 header which contains additional power and clock signals next to ...

Sun SPARCstation IPX
The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth. The Sun's radius is about , or 109 times that of Earth. Its mass is about 330,000 times that of Earth, comprising about 99.86% of the total mass of the Solar System. Roughly three-quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron. The Sun is a G-type main-sequence star (G2V). As such, it is informally, and not completely accurately, referred to as a yellow dwarf (its light is actually white). It formed approximately 4.6 billionAll numbers in this article are short scale. One billion is 109, or 1,000,000,000. years ago from the gravita ...
