About us
The company was started in 1971. The name Aleph One was chosen to be non-specific. We started selling computer products in 1984.
In 1984, we were using Biofeedback instruments to control video games on Acorn BBC Microcomputers This led to the development of processor cards for Acorn computers (which had their own operating system) which could run the DOS and Windows operating systems. Acorn users ran Windows applications in a window!
When Acorn left the computer market we used our knowledge of other operating systems to move into Linux and then into embedded Linux. We have developed the yaffs File System specifically to provide a robust journalling file system for NAND Flash chips, and it is now widely used in high-volume products.
