The T4005 was an incredible product for its day. It contained an 11" DVST display and a Graphic Display Controller. The controller could drive one of 4 displays and in conjunction with software on the host computer could provide scaling, offsetting, magnifying, framing, and augmenting of the graphic output. It operated within an 8K X 8K address space and provided a simple user interface. This T4005 brochure describes some of its features. Click on the image to view the PDF.
