MS-DOS style boot and command workflows, keyboard-first interaction and era-appropriate peripherals.
Operating System Experience
Explore how computers boot, initialise hardware, load an operating system, accept commands, run programs and connect peripherals.
From power-on to applications
Windows, Linux, Unix/BSD and macOS concepts, shells, processes, filesystems, services and development tools.
IBM i, z/OS, AIX, Solaris, HP-UX, OpenVMS, HPE NonStop and researched Japanese mainframe environments.
MOUSE OFF / MOUSE ON and era controls affect only the HEPC viewport. They must never disable the user's real operating system input.
Power On → Firmware → POST → Boot Device → Bootloader → Kernel → Drivers → Services → Login or Shell → Applications.
DOS-style keyboard-first learning, graphical microcomputer history and modern Windows, Linux, Unix/BSD and macOS concepts are represented as education simulations.
Keyboard, mouse, monitor, storage, printers, serial, parallel, networking, audio, GPU, accelerators, sensors and industrial I/O are part of the learning taxonomy.
All existing public simulation, Coding Studio, Intelligent Coding and current working pages remain unchanged. New HEPC features start from the new Programming Studio onward.
