    Before re-writable storage devices, such as tape drives, become popular for the DEC PDP-8, owners had to rely on paper tape. This was fine for loading programs on pre-punched tape, but left the problem of how to put new data onto punched tape and how to edit existing data. This could be done of...   Read More
