Report: The 630 Multitasking Graphics Terminal
Yoram Bernet, J. Michael McCarthy · AT&T Technical Journal · 1987
The 630 MTG (multitasking terminal with graphics) implements technology that has its origins in AT&T's Blit1terminal and its successor, the Teletype® 5620 dot-mapped display (DMD) terminal. (Panel 1 defines acronyms used in this paper.) With the 630 terminal, substantial progress has been made in display quality, terminal packaging, circuit design, connectivity, and firmware functionality, while the cost of delivering the technology has been greatly reduced. These innovations have led to greatly improved business prospects for this class of device, because several major applications will be delivered to their users via 630 terminals.
