This machine was coupled with a very early In 1990, the Pixar Image Computer was defining the state-of-the-art in commercial image processing. This can be expanded to three CHAPs, two video boards, and six memory boards. The PIC runs on 190 to 250 volts of AC power @ 20 amps, single phase, at 47 to 63Hz. In 1987, Pixar redesigned the machine to create the P-II second generation machine, which sold for $30,000.In 1988, Pixar began the development of the PII-9, a nine slot version of the low cost P-II.
These consist of four CHAPs, two video processors, two off-screen memory (OSM) boards, and an overlay board for NeWS (a PostScript-based windowing system). Memory bandwidth is at 480 MB/sec.
In 1984, the Graphics Group, Lucasfilm's computer division, showed off the prototype of the Pixar Image Computer at the SIGGRAPH computer graphics conference, in addition to a partially-completed version of Released commercially for the first time on February 3rd, 1986, some time after Steve Jobs bought out the Graphics Group and renaming it Pixar, the Pixar Image Computer was intended for commercial and scientific high-end visualization markets, such as media production and medicine.
This decision was the catalyst for Pixar to lay off its hardware engineers and sell the imaging business. The standard video output board of the PIC has a high standard screen resolution of 1024 x 768 pixels interlaced, and a high broadcast quality standard RGB output of 525 lines (625 lines for PAL regions). Pixar Unified. The minimum configuration holds six boards, comprised of one CHAP, one video board, one memory controller, and three 8 MB memory boards. The original PIC boasts a rack-mounted box chassis measuring 21" x 19" x 30" with 12 slots for expansion boards, and weighs 100 to 150 lbs (45 to 68 kg). The P-II could have two Channel Processors, or Chaps. The P-II (Model 820204) uses a chassis that could accommodate four expansion boards, eight less than the original, considering that it is meant to be a lower cost model. The chassis could hold 4 cards. The Pixar Image Computer (also known as the PIC for short) was a graphic designing computer originally developed by the Graphics Group (which would later become Pixar). It has 3 color lookup tables (10 bits in, 10 bits out), 10 bits per DAC, and a video bandwidth of 480 MB/sec. The PII-9 and its associated software became the prototype of the next generation of commercial "low cost" workstations.
"It was built to be part of a pipeline, but as we developed it we realized we were competing with The Pixar computer business was sold to Vicom Systems in 1990 for $2,000,000. It proved to be ahead of its time, and had generated a lot of single sales. It had a price tag of $135,000, but it had also required a $35,000 workstation from Sun Microsystems or Silicon Graphics to operate it.
Fewer than 300 Pixar Image Computers were ever sold. The Pixar Image Computer is a graphics computer originally developed by the Graphics Group, the computer division of Lucasfilm, which was later renamed Pixar. The PII-9 could hold 9 cards (4 Chaps, 2 video processors, 2 Off Screen Memory (OSM) cards, and an Overlay Board for the Pixar Animation Studios' own P-II Pixar Image Computer. The Pixar Image Computer comes with an extensive software package, which was developed in-house by Pixar under Unix 4.2 in both the C and Assembly programming languages, for developing applications. It also delivers state-of-the-art light path guiding based on work from Disney Research for computer learning.
Vicom Systems filed for Many of the lessons learned from the Pixar Image Computer made it into the Low Cost Workstation (LCWS) and Commercial Analyst Workstation (CAWS) program guidelines in the early and mid 1990s. However, it did not sell in quantity. A variant of the P-II features five expansion board slots. By This system was aimed at high-end government imaging applications which were done by dedicated systems produced by the aerospace industry, which cost a million dollars per seat. The system interfaces to the host machine via the SYSBUS. However, this had little effect on sales, despite the machine's ability to perform CAT scans and show perfect images of the human body. Aimed at commercial and scientific high-end visualization markets, such as medicine, geophysics and meteorology, the original machine was advanced for its time, but did not sell in quantity. The terms were: Buy a million-dollar scanner, and get a $30,000 3D visualization system free.
The imaging business was sold to Vicom in 1990 for $2,000,000.
The PII-9 uses a similar rack-mounted form factor to the original PIC, with the exception that it could accommodate nine expansion boards, rather than twelve. It is slightly smaller than the original PIC at 21" x 17.5" x 23.5", and weighs 140 lbs (63.5 kg). A rare Pixar Image Computer that was originally developed by the Computer Division of Lucasfilm has surfaced on eBay with a $25,000 price tag. In an attempt to gain a foothold in the medical market, Pixar donated ten machines to leading hospitals and sent marketing people to doctors' conventions. There were no high volume buyers in any industry. Pixar did get a contract with a manufacturer of CAT Scanners, which sold 30 machines. The PIC did not have a direct user interface, meaning that it cannot be used on its own.

The pixels use 12 bits for red, green, and blue, plus 12 bits for the alpha channel. For this, it requires a Unix-based workstation acting as a host machine to operate it (at least to provide a keyboard and mouse), from brands such as Sun Microsystems or Silicon Graphics.
The government mass deployment that drove the PII-9 development occurred in the late 1990s, in a program called Integrated Exploitation Capability (IEC). It was designed for the high-end visualization markets. The host machine can be positioned up to 30 feet from the PIC.
