ORDINATOR first video board
The first video board of the ORDINATOR was built to generate the
video signal for a single display monitor. It is a pure output
device that continually encodes the contents of a region of
system memory into a video signal. Functionally, the board
is identical to the second video board,
except for the memory segments that it occupies. Under TS,
this board is coupled with the first keyboard and known as
the VIDEO0 device.
The first video board was built using wire-wrap techniques that
proved to be cumbersome for maintenance; the second board used
our conventional Teflon wiring system.
