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: [ Ссылка ]

The Sinclair ZX Spectrum build of Collapse OS runs on the 48K model. This is the second demo, showcasing the driver for tape storage abstracted as a block device within the OS. The zasm assembler reads source files from tape (dev3) through the file handle #0 (dev1) and writes the binary into the memory-based blkdev (dev0). A package of shell extension routines is used for conversion of memory-based and tape-based binary files to and from CFS (Collapse file system).

Porting Collapse OS to the out-of-the-box ZX Spectrum 48K with tape storage is the work in progress.
