16-bit ALU), and 4090 and all 418x and 419x systems (eighteen Am2901 each, 32-bit integer ALU or 8-bit exponent, 64-bit Double Precision floating point ALU). The DEC KS10 PDP-10 model. The UCSD Pascal P-machine processor designed at NCR by Joel McCormack. A number of MAI Basic Four machines. The Tektronix 4052 graphics system computer. The SM-1420, Soviet clone of PDP-11, used Soviet clone of AM2901 perhaps also used in others. The Lilith computer designed at ETH Zürich by Niklaus Wirth. Atari's vector graphics arcade machines Tempest, Battlezone, and Red Baron each used 4 Am2901 ICs in their "math box" auxiliary circuit boards. Atari's raster graphics arcade machine I, Robot, the first commercial game featuring filled polygons, included a math processor built around four AMD 2901 chips. Pixar Image Computer, 4 Channel Processors each with 4 Am2900's Simulation Excel (Sim-X), Oslo, Norway: Typographical workstation / typesetter; one of its four processors was a 16-bit microcoded calculation and transformation engine built from four 2901 slices and one 2910 address sequencer. The Sim-X machine used a 16-bit integer multiplier to optimize graphical transformations. The machine debuted in 1983 and the company shut down in 1987. Eventide H949 Harmonizer; four Am2901 chips (and several microcode PROMs) are used to generate addresses and generate reference voltages for the DAC system audio was not processed in the 2901 ALU section. Many Siemens Teleperm and S5 PLCs used for industrial control were built using the 2900 series. AT&T 3B20D processor. Metheus / Barco Omega 400 and 500 Series graphics systems; four Am2901 chips (and eight microcode PROMs) were used to perform graphics operations on this 1982 display processor. Geac Computer Corporation 2000, 6000, 8000, and 9000 were all based on 4 x AM2901 chips. The GEAC 9500 was based on the AM29101. The GEAC 2000 was used in pharmacies. The other models were used in library, banking, and insurance automation. The 2000 was a single processor unit. The 6000 and 8000 contained four processors, each dedicated to one of comms, disk, tape, or program processing. The 8000 had local processor memory whereas the 6000 did not. The 9000 and 9500 were AMP systems with up to 8 CPU modules. AES Data Systems C20 Multiuser Word Processors. AES of Montreal designed a series of modules and systems based on their AES-800 bit-slice processors. 8- 12- and 16-bit buses were part of the design. Later iterations of the Ferranti
