In 2001, Eyring Corporation released a 32-bit reconfigurable RTOS called EYRX. I remember downloading the documentation and programmer guide from their Web site. Strangely, no traces of that OS can be found anywhere on the Internet (except for the brief mention on a defunct site). The system is not even on the list of real-time operating systems, as if it never existed. Does anyone know what happened to EYRX?
What, this documentation?
I found this by searching for Eyring on the Internet Archive, finding Eyring.com, going to their earliest 2002 snapshot and clicking on the EYRX link.
Unfortunately, the operating system itself was hosted on an FTP server, and those aren't archived by the Internet Archive. So we'll see if somebody else can find it.
