CR11 Card Readers
From Computer History Wiki
The CR11 Card Readers were a series of punched card readers OEM'd by DEC from several vendors; all were controlled by the CR11 Controller. The specific units were:
- Documation M200
- Documation M300
- Documation M600
- GDI 100
- GDI 100M
The first two Documation units could read 80 column cards at 300 cards/minute, the last at 600; the GDI units could handle 200 cards/minute.
The GDI 100M read 40 column marked cards.
