final brainteaser for the day

Jerome Fine replies: YES!! *grins* (You just asked "Can you" - not to actually describe them!) Now, to actually describe them "all", I don't think it is worth while to spend all that amount ot time (a few centuries) or the space. But, The major 3 are (there are many more): RSTS/E RSX-11 RT-11 which is the only one I currently use. It would take about 10 years to describe completely - the DOCs for V5.07 are about 18" high double-sided 8" * 11" sheets without the binders. The program listings for each distinct version of the operating system are about the same size and there are at least 2 major flavours, unmapped (RT11SB and RT11FB) and mapped (RT11XM and RT11ZM) with significant differences (15% to 25%) between the unmapped and mapped flavours. The listings for the utilities are probably another 48". The DOCs can be purchased. The source code licenses can also be purchased. DEC probably had internal documentation as well, but no information seems to be publicly available, including the DEC (and the Mentec) RT-11 Bug List. Megan Gentry can probably confirm the information about the DOCs and the source listings. There is probably an NDF (Non-Disclosure Agreement) that prevents anyone who knows about the "secret" stuff from even admitting that they know anything about the "secret" stuff. Otherwise, those who know and may even have copies could at least say how many pages of internal documentation existed and how many bugs are in the "secret" DEC (and the Mentec) RT-11 Bug List. *grin* Perhaps you can understand why I suggested it would take about ten years to completely describe RT-11.
