Abstract
An internally programable data entry system having a microprogram memory, a microprocessor logic and programable storage means for storing program data and constant data. The data entry system permits program data and constant data to be automatically loaded into the storage means from prepared punch cards having indicia and data thereon which identifies the type of data being entered in the storage means, the address for storing said data and a chained address which indicates the address of the next program to be used after the program currently in progress is completed.
Claims10
An internally programable data entry system for preparing data cards comprising:
- data entry means having manual and automatic entry load modes,
- card input means for receiving prepared cards and blank cards, said prepared cards having indicia means and data thereon,
- card reading means connected to said card input means for reading both indicia means and data entered on a said prepared card,
- said indicia means on said prepared card indicating whether said data on said card is program data or constant data,
- buffer output means connected to said card reading means for receiving and storing indicia means and data read from said card,
- control means responsive to said indicia means for automatically storing said indicia means and data from said buffer output means in a program data storage area or a constant data storage area, and
- program and constant data storage means for receiving and storing said program data and said constant data from said buffer output means under control of said control means as indicated by said indicia means.
An internally programable data entry system for preparing data cards comprising:
- data entry means having manual and automatic load modes,
- card input means for receiving prepared blank cards,
- card punch means connected to said card input means for entering indicia means and data into a blank card,
- input buffer means connected to said data entry means for receiving and storing indicia means and data from said data entry means,
- control means responsive to said indicia means and said data for automatically entering said indicia means and data from said input buffer means into said blank card, and
- manually operable keyboard means in said data entry means for setting a manual preparation mode and homing said card to the indicia position and for manually entering said indicia means and said data into said input buffer means.
