The board provided a 80X24 line character display. There was a keyboard
interface and all the usual character display enhancements, even block mode
editing. The board also had good I/O port setup flexibility and its
own onboard RAM. It had the nice extra ability to use either a
positive or negative status bit (any bit), for any of 256 I/O ports. It was
somewhat similar in operation for example to the
SD
systems VDB 8024 board. You could also have a white on black
or black on white text display.
