Collapse OS on the ZX Spectrum

Collapse OS is an operating system for the improvised resource-constrained devices. Maintained by Virgil Dupras, it aims to provide means for microcontroller programming using this kind of hardware. This version is written in the Z80 machine code. The official Collapse OS website: This Sinclair ZX Spectrum build of Collapse OS runs on the 48K model. The kernel is assembled into RAM, with the editor and assembler applications included into the binary. The BASIC ROM routines are accessed through the provided I/O API. For this demo, operations are done on a small RAM-based filesystem. Porting Collapse OS to the out-of-the-box ZX Spectrum 48K with tape storage is the work in progress.
