OS/8 Device Handlers for PDP-12 Core

This document provides a technical write-up for OS/8 device handlers designed for a PDP-12 system equipped with LINCtape and 32K of core memory. These handlers aim to reduce tape shuffling by utilizing upper core memory for directories, system areas, or files. The documentation includes details on four different versions of the build utility (BUILD), configured for various system/non-system device setups. It also covers usage commands for initializing and restoring tape directories. This software requires OS/8 Version 3.
