SVC

The SVC video controller has all the features you need for high-speed text display. Its 80 x 25 format can use the 25th line as a non-scrolling status line, and attributes may be set for inverse video, reduced intensity and flashing, either on a screen-wide basis, or character by character using the top bit.

The SVC can generate interrupts. It can accept characters at a maximum rate of approximately 15000 per second. It produces standard RS170 composite video, separate TTL syncs and video, and operates with 50 Hz monitors.

The SVC is I/O mapped on the STEbus occupying four I/O locations.
