A graphical desktop for the ZX Spectrum
TL;DR
A graphical desktop environment for the ZX Spectrum 48K was developed in Z80 assembly, featuring overlapping windows, menus, and a file manager, all fitting within 48K of RAM. This project showcases the creative potential of retro hardware, providing valuable insights for developers working with similar constraints.
✦ Why It Matters
Explore the provided measurements to enhance your own projects on retro hardware.
Key Takeaways
- Utilize precise timing measurements for performance tuning.
- Implement a real heap for efficient memory management.
- Design an event queue to handle user input effectively.
- Explore graphical interfaces on constrained hardware for innovative solutions.
How It Works
The desktop operates by managing overlapping windows with a z-order and focus, allowing for smooth interactions. It employs a sixteen-slot event queue to handle input events, ensuring that the main loop remains efficient and free of window-specific code.
Memory management is achieved through a real heap, which allocates buffers based on window size, optimizing the limited RAM available.
