IBM 1410 FPGA: Wrong Wrong Length Record

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. The current FPGA from the ALDs implementation does not create an error stop, it simply Continue reading "IBM 1410 FPGA: Wrong Wrong Length…
