RTEM-11

Introduction

This page is dedicated to restoring and improving RTEM‑11 assembled from individual files found on the Internet. When it all started, I only had a few files from the RTEM‑11 V01.00 where RT‑11 V04.00 was used as a bootable system. But the most necessary files were not found. And of course, there was no talk of any support for dates after 1999. Since then, a lot of work has been done, RT‑11 was upgraded to the latest version V05.07 with extended device unit support, and the result of this work can be found on this page.

RTEM‑11 has been tested under the following systems:
