2501 Card Reader

• Model A1 reads 600 cards per minute.

• Provides separate high-speed card input for improved throughput performance.
• Standard 1200-card-capacity hopper and 1300-card-capacity stacker.
• Operates on a cycle-stealing basis, with one core storage cycle per card column.
  

1231 Optical Mark Page Reader

• Optically reads standard #2 pencil marks on a source document, and transfers information directly to 1131 Central Processing Unit.
• Can maintain a document throughput of 2000 per hour.
• Once source documents are placed in hopper, the 1231, under stored program control, requires no further operator intervention.
• In a single pass through the reader, marks are read and checked, and information is transferred to the processor on a fully buffered interrupt basis.
• Master mark data is transferred to the 1131 only during reading of the master mark sheet.
• Source documents measure 8-1/2" by 11", with up to 1000 marking positions.
• Mark discrimination compares marks against a predetermined level. Data sheets can be rejected under program control if a weak or invalid mark is detected.
• Cannot be attached to system using a 2501 Card Reader.
