Keyboard and Display Program and Operation

Alan Green
January 1966 

The Keyboard and Display Program described in this report is included in the Flight 202 Program (originally called CORONA). This report brings E-1574 up to date.

Keyboard and Display Program and Operation

Alan I. Green and Robert J. Filene

The Keyboard and Display program described in this report is included in the Flight 278 Programs (originally called SUNDISK and SUNDXNCE).
     The lists of nouns and extended verbs are incomplete. They differ somewhat in CSM and LM and are subject to frequent change. The most complete and up to date information for these is best obtained from the latest revision of MTT/IL "Flight 278 Memo 17", or from the "Assembly and Operation Information" log section at the beginning of the program listing itself.

Computer Displays

Eldon Hall
January 1962 

The enclosed discussion of computer displays is taken from the minutes of a monthly progress meeting. This presentation is based on a very early iteration of the display problem. Substantial changes are expected to result from the overall display analysis which is underway.

Digital Development Memo #267: Block II Keyboard and Display Program

Alan Green
July 28, 1965

General Remarks (excerpt)
     The Keyboard and Display Panel for Block II is very similar to that of Block I. There are still "2 character" displays for major mode, verb, noun; and three "5 character" displays for data (each of these may also have sign). The Keyboard has the following keys: +, -, 0 through 9, CLEAR, ENTER, VERB, NOUN, RESET, KEY RELEASE.
     Operationally the Keyboard and Display System Program differs little from the Block I system. Block I operation has been thoroughly described in E-1574 and modified by Digital Development Memo #245. This report assumes a familiarity with the above cited reports, and will serve to point out differences and changes from the Block I operation.
