The Ramtek 9000 series image display system was used for this project. Ramtek created a 32 bit interface to the Interdata for this purpose. Ramtek supplied image display systems which supplied square displays (256x256 or 512x512) as its competition did but also screen matches such as 320x240, 640x512 and 1280x1024. The original GE CAT Scanners all used the Ramtek 320x240 display. Some prices of the day may be on interest. A keyboard, joystick or trackball would each sell for around $1,200. A 19" CRT had a OEM price of around $5,000 and this would be purchased from Igagami in Japan. The production of a single CD master (around 13") was $300,000.
