  4. IBM 1410 FPGA: Overlapped I/O Fix

    (The Computer Collection)

    Overlapped Tape I/O is generally working OK now.

  5. IBM 1410 FPGA: Wrong Wrong Length Record

    (The Computer Collection)

    The vast majority of errors noted by the tape diagnostic T020C related to wrong length record errors, particularly when a tape operation writes from the last character of storage (39999 in my current 40K implementation), usually starting at location 39990.

  6. IBM 1410 FPGA: From USB Serial to UDP over Ethernet

    (The Computer Collection)

    Seeing that some of the problems that I had identified with the Tape Adapter Unit (TAU) implementation could be or might be traceable back to the fact that I was using a 115,200 bps serial over USB to communicate between the 1410 FPGA implementation and t…
