Dragonfruit: A 68k/Dragonball Palm device emulator for ESP32 devices
TL;DR
Emulators for older devices are scarce, limiting access to legacy software. Dragonfruit is a 68k/Dragonball emulator built in portable C that runs on ESP32 hardware.
✦ Why It Matters
Engineers can leverage Dragonfruit to explore and develop applications for legacy Palm OS devices.
Key Takeaways
- Explore legacy software using Dragonfruit emulator.
- Develop applications for Palm OS on modern hardware.
- Utilize ESP32 for retro computing projects.
- Contribute to software preservation efforts.
Full Summary
Emulators are essential for preserving and accessing legacy software, particularly for devices like the late-90s Palm handhelds. Dragonfruit is an emulator specifically designed for the Motorola MC68EZ328, also known as DragonBall EZ, which is a 68000-based system-on-chip.
Built entirely in portable C, it includes a 68000 interpreter and models of the DragonBall's peripherals such as the interrupt controller and LCD controller. The emulator operates without platform dependencies, making it suitable for both PC development and deployment on ESP32 hardware.
The M5Paper, an ESP32 board with an e-ink display, serves as the reference target, enabling it to function as a working Palm IIIx. Users can boot the Palm OS 3.x, complete the initial setup, and utilize stylus input for handwriting recognition.
This development opens avenues for retro computing enthusiasts and software preservationists.
