An imaging mode in which the CRT Beam skips over black pixels.
One of nine CRT intensities (0 through 8). The user or the internal
system assigns a subset of intensities to red, green, and blue colors
in a given mode.
A circuit over which information passes.
A vacuum tube in which an electron beam, directed at a
phosphor-coated glass screen, causes a point on the screen to
glow. As magnetic coils deflect the beam, the point of light moves
across the screen. Variations in the intensity of the beam create a
visible display on the screen.
During a check, a sum of bits or bytes in a quantity of data ensuring
that the data is accurate.
A set of 5 switches in a plastic box (a "Dual In-line Package" or
DIP) which can be set by hand.
A form of memory, continually refreshed, possessing both read and
write capability. Memory contents are lost when the power is t u r n e d
off.
An operator-induced fault, a programming fault, or a data
discrepancy.
A hardware-induced failure.
A movable wheel containing three color filters and one neutral filter
which reside in the optical path and which color the imaging beam.
