>and for those who have no real idea about the IBM1401 Back in the early to mid 1960s the site I was working at had a 1401 that ran an order entry system that used 1311 disks. The product, customer and other direct access files were on the disks. The invoices were printed and a tape with billing information was written. The input was cards converted from paper tapes fed by the various warehouses and shipping documents were punched out to be split by warehouse and sent to the warehouses by dedicated keypunches that could teletype the orders to warehouses (special modification done by the person who became my boss). It took about 3 hours from entry of order to shipment. This was first replaced by 360/30 with 1401 emulation that ran the 1401 emulation and a very stripped version of QTAM so the card input that the 1401 program saw was actually input from QTAM and the punched card output became direct transmissions to the field. The 1401 direct access files became 360 ISAM files on 2311s.
