Yes .. I remember the concept of sectors on those disks. Wang Basic didn't have the concept of indexes on the data .. we just told it to go to a certain sector on the disk and read the data. Or we could sequentially read through each sector .. but we certainly couldn't tell it to go find a particular record.
