Glitch Works XT-IDE Rev 4 — 8-Bit ISA IDE Controller

The Glitch Works XT-IDE rev 4 is an open-source 8-bit ISA IDE controller board that enables the use of modern 16-bit IDE devices (CompactFlash adapters, DOM modules, hard drives) on vintage IBM PC/XT, AT, and compatible systems. Designed in KiCad and licensed under GNU GPL v3.0, the rev 4 improves on the rev 3 with better silkscreen, larger jumper pads, corrected latch read/write timing, additional Slot 8 Support test points, and consistent parts numbering for easier kit assembly. When paired with the XTID

Try Word Unperfect

Current binary

The main public test build is a Linux x86_64 host package. It starts in the WordPerfect-style full TUI by default and uses libc-hosted input/output paths rather than DOS calls. This build includes Edit-menu block commands, arrow-key submenu navigation, console mouse menu coverage, verified append/export behavior, and refreshed font attribute rendering.
