An experiment: how much Forth can cram into only 510 bytes?

A monolithic 16-bit x86 OS forged in Assembly. Features a custom FAT12 driver, segmented memory architecture (0x1000/0x2000), and a syscall jump-table for bare-metal application development.

VizOS adalah kernel 16-bit real-mode ringan berbasis Assembly murni. Fitur utamanya, Tokenizer Transparan, memvisualisasikan logika parsing perintah secara real-time. Dibangun tanpa pustaka eksternal, proyek ini menjembatani logika tingkat tinggi dengan eksekusi mesin, ideal untuk edukasi OS.

This repository contains wmake style makefiles and patches to build Lua on Open Watcom 1.9 or later. This allows Lua to be cross-compiled for several legacy Operating Systems as far back as 16-bit DOS.
