Does anyone use RT-11?

Jerome Fine replies: Yes that seems to be the goal, but what will you do with RT-11 at that point? If playing games is the objective, then RT-11 is not really being used except to start the process. Based on the few responses, I guess that no one is writing any programs, let alone modifying any utilities. And almost certainly, no one seems to be modifying device drivers or the operating system itself. If anyone is actually interested in that aspect, please let me know. Tim also sent a short reply which was very appreciated. However his job and family commitments are such that Tim no longer has any time to give to RT-11. But any help in locating old source files would be appreciated. I have been unable to locate the most recent source code for SDX.SYS which places most of the code and data in high memory. Also missing is the most recent source code for MACRO-11. The Y2K source code modifications would also be interesting, but are not extensive. One interesting (and almost trivial) modification to the operating system is support for READ ONLY files. The resident monitor requires modifications in only a couple of areas to support READ ONLY files. However, DIR and PIP require far more - is anyone interested? Probably the user visual interface is the most easily decided. Protected files are shown by DIR with a "P" beside the file name. If the file is READ ONLY, then an "R" can be used. I suggest using "r" (lower case) when the file is both READ ONLY and Protected. Does anyone have any other suggestions - other than using TWO characters as with "PR"? When two files are displayed per line (as is the normal case) and the starting block numbers are included, 40 characters per file description is just too limited and more than 80 characters per line is not recommended. Now that the year requires 4 digits, there is not enough room for even 2 more characters on the line. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.
