 # FOSS-RCX-ROM
-An open source implementation of the Lego MindStorms RCX ROM
+An open source implementation of the Lego MindStorms RCX ROM,
+which has been extracted from the larger
+[brickEmu project](https://github.com/BrickBot/brickEmu).
+
+These same source files have also been added to the
+[brickOS-bibo project](https://github.com/BrickBot/brickOS-bibo)
+as "rom" targets in the Makefiles.
+
+Given the nature of this project, this source code is likely to
+see little change, but the master version of this source code
+is currently considered to be the copies in the aforementioned
+[brickOS-bibo project](https://github.com/BrickBot/brickOS-bibo).
