IBM 705

IBM 705

The 705 was a followon to the 702 with the same type of architecture. There were three models, I II and III. It had core storage with up to 60 000 characters. The card readers, punches and line printers could be operated either online or offline. Each consisted of a control unit and the peripheral unit (reader, punch or printer.) When online they read or wrote directly into memory. When offline a tape drive was connected to the control unit which could then read to tape or punch or print from tape. These units were also available separately from the 705 and were often used with other 700-series machines as offline peripherals.
