Abstract
Abstract A self-contained, unitary console for keyboard editing of wireservice or blind keyboarded text. The text is displayed on a cathode ray tube and, after being edited, may provide the input for a computer or an automatic typesetter. A ''''hard-wired logic'''' interface, connected ahead of the input to the memory in the console, strips or otherwise modifies special codes read in from the input tape to provide the desired instructions to the cathode ray tube display.

An apparatus according to claim 1 wherein said visual display means comprises second means responsive to said coded data for controlling the visual appearance of a character displayed in response to a character code and said first means includes means operative in response to a first special code comprising an UPPER RAIL code in the input text to change said input data to effect a change in the appearance on said visual display means of a character or characters whose codes follow said UPPER RAIL code in the input text.
Claim 4
Dependent Claim
65 words
An apparatus according to claim 2 wherein said visual display means includes a cathode ray tube for displaying the characters and said second means is actuated in response to coded data to control the brightness of the display, and said first means comprises means for modifying character codes following said UPPER RAIL code to provide a first brightness for said following character codes when displayed.
Claim 5
Dependent Claim
68 words
An apparatus according to claim 3 in which said first means is responsive to a special code comprising a LOWER RAIL code in the input text to modify said encoded input text data to cause the brightness of the displayed character or characters whose codes follow said LOWER RAIL code to have a brightness substantially below the brightness of the character or characters following said UPPER RAIL code.
Claim 6
Dependent Claim
55 words
An apparatus according to claim 4 wherein said first means comprises means to prevent said UPPER RAIL and LOWER RAIL codes from being entered into the refresh memory and means for adding to the character codes which follow said UPPER RAIL and LOWER RAIL codes an additional bit which designates the corresponding level of brightness.
Claim 7
Dependent Claim
57 words
An apparatus according to claim 1 wherein said first means is responsive to said first code which is a special SHIFT code in the input text to modify the encoded input text data to cause the character or characters whose codes follow said SHIFT code in the input text to be capitalized on said visual display means.
Claim 8
Dependent Claim
58 words
An apparatus according to claim 6 wherein said first means comprises means operative in response to a special UNSHIFT code in the input text to cause said visual display means to modify the encoded input data to effect display in lower case form for the character or characters whose codes follow said UNSHIFT code in the input text.
Claim 9
Dependent Claim
51 words
An apparatus according to claim 7 wherein said first means includes means to prevent said SHIFT and UNSHIFT codes from being entered into the refresh memory and means for adding to the character codes which follow said SHIFT and UNSHIFT codes an additional bit which designates capitalization or lower case display.
Claim 10
Dependent Claim
42 words
An apparatus according to claim 1 wherein said first means includes means for detecting a standard end-of-paragraph code sequence in the input text and for converting same into a different code format for effecting an end-of-paragraph operation of said visual display means.
