Ondisk-Offdisk

This document outlines the usage of two programs, OFFDISK and ONDISK, which allow users of a PDP-12 system with a DF/DS-32 disk to dump disk contents onto Linctape and restore them later. The programs operate under the DIAL monitor, and allow for the storage of up to five disk images on a 1600-block Linctape. The manual covers operation procedures for both programs, including error handling, hardware requirements (8K PDP-12, VR-12 scope, TU-55 tape transports, and DF-32 disk), and storage specifications.
