[edit] Interfaces
Scan Data Terminal (SDT) Based on DEC LSI-11/02 CPU and built on Q-BUS and UNIBUS architecture, featured two 8" floppy units (first Shugart, then NEC), a TeleVideo display (models 910, 905) and a dot matrix serial printer. Connected to the analyse scanner (Scanner I/F board) via a 19.2kbps serial line, allow job storage, multiple batch scanning (Multran) and a sort of page layout (Magnaplan). Operating system: DEC RT-11
Scan Station Based on DEC LSI-11/23 CPU and built on Q-BUS and UNIBUS architecture, had all SDT features, plus an interface towards CDC9766 300MB removable drives via a System Industries 9500 controller, an image scanning interface (two boards on scanner and a Scanner interface board). Optional, a text kit (Textran) featured a Panther INPut (PINP), a couple of dedicated boards that drive a dedicated text hardware within the EDG backplane, for separated text output.
QuickView Based on IBM PC, with Microsoft Xenix and Microsoft Windows 2.1.
QuickView II Based on IBM PC, with SCO Unix
ScanView Based on DEC LSI-11/73 CPU and built on Q-BUS architecture, incorporates a scanner input hardware for storing on internal hard disc. The HR image can be retouched and modified, with aid of mask layers, displayed on embedded Barco calibrated monitor, and then outputted on film. All graphic display functions are performed by the Graphic Cabinet, with 4x1MB video memory boards (CMYK), a color converter board (CMYK to RGB), three Video controller board (ECL technology). Operating system: DEC RSX-11M+
ScanView II Same as ScanView, with improved keyboard (trackball and bigger diplay) and a better input technology.
Sirius 250 A broad planning console, using an LSI-11/73 CPU with dedicated boards (Picture Interface, Picture Processor) and featuring a tablet, keyboard and mouse input controls. Operating system: DEC RSX-11M+
ImagEdit Similar to ScanView II, but arranged as console station with a mouse input control. Operating system: DEC RSX-11M+
[edit] Studio systems
Studio 800
Planning system with tablet and layout monitor only. User interface via teletype (Silent 700) Operating system: DEC RSX-11M+
Studio 820
Studio 840
Studio 860
Dual computer studio: Colour Composition Station (CCS) for planning tasks, with both layout and graphic calibrated Barco monitors, and File Manager System (FMS) for assembly and disc-related tasks. The two DEC LSI-11/73 processors are connected together with a 2x20-wires flat link. Storage on CD9766 drives. Archiving is available on TA-1 tape drive. Optional: text assembly subsystem (Textran), using a dedicated board pair (Panther Assembly, PASM). Operating system: DEC RSX-11M+
Studio 870
Studio 880
Studio 890
Studio 8X5
Upgraded Studio systems, using fixed discs instead of removable CDC ones. Typical capacity 340MB, 600MB, 825MB each. Archive is available on TA-3 half-inch tale drive. Operating system: DEC RSX-11M+
Studio 910
New design Studio, evolved from Studio 875
Studio 920
New design Studio, evolved from Studio 895
Studio 9500
Unix-based Studio System, built on Motorola 68020 CPU and 8MB system RAM. All main task are performed on the System Interface Adapter (SIA) board, that hosts 3 SCSI buses and a graphic accelerator card (Molar). Image discs are 3x300MB, with an optional 6x300MB disc tower. An Exabyte cassette tape drive is available as standard for image archiving. Operating system: AT&T Unix SVR4
Studio 9500 II
Improved version, with 16MB RAM and 1GB image discs.
Studio 9700
RISC-based Studio System, with MIPS 3000 CPU. All main tasks are performed on the Cepheid board and the SIA board.
ColorSpace
Studio 9500-based retouching station, with a dedicated graphic cabinet (Viper). The Viper chassis performs video modifications using Video General Interface Processor boards (VGIP), Video Frame Store boards (VFS) and Video Frame eXtension boards (VFX). Images are converted from CMYK to RGB for display, using the Colour Converter board, featuring a parallel array of 100 ASICs for realtime displaying. Operating system: AT&T Unix SVR4

[edit] Custom technologies
Electronic Dot Generation (EDG)
The EDG technology allows screens to be created on film without the need for a contact screen. The argon-on laser (wavelength 488nm) flows through a special-coated 6-way beamsplitter, splitting the single beam into 6 parallel rays and independently modulated via a crystal core electrostatic modulator, with a fixed polarizer in front. A Modulator Amplifier Board (Mod Amp) is driven by six text-information analog channels, and applies a proportional high voltage to modulator electrodes, rotating the light plane of each beam and therefore interfering with the polarizer, thus modulating the light intensity on film.
The EDG screen is built to be etchable as the contact screen does, with soft edges and conserving a peak > 4.5ND density at the center of the dot.
With a specific optical turret system, EDG could create a wide rulings range.
