It ran DOS on one and XENIX on the other. Used by many organizations that needed C/PM or DOS and XENIX support. In my case, it was a patient monitoring system with DOS and XENIX running on it. The user could press a key on the keyboard to switch between OS's. I think the XENIX system ran a file share the DOS system could access if I recall correctly. Any SpaceLabs retirees out there? | |

| Mar 2, 2023 at 8:49 | comment | added | ecm | dosemu was started in the 1990s I believe. dosemu2 is a much later creation based on the original. They both run a DOS but provide a file system redirector so the DOS can access Linux host directories as DOS drives. The redirector is based on MachFS, which originates from a DOS layer for Mach. | |
