Abstract
A high-speed interface for use between a computer having a Unibus data transmission system and a Tektronix graphics terminal includes elements for converting pairs of coordinate words from the host computer into five seven-bit bytes usable by the Tektronix graphics terminal. The interface is capable of emulating a standard interface device and is also capable of cyclically refreshing the Tektronix graphics terminal so that it can operate in a write-through mode.
