Probably, but the authoratitive source for this sort of thing is the manual that matches the version of RT you're interested in. That's easy: SWAP.SYS, TT.SYS, DY.SYS (or DX.SYS or whatever driver your hardware uses for the 8" drive), and a monitor (RT11SJ.SYS). This gives you a bootable minimal floppy which is capable of doing very little :-). Almost certainly you want to put PIP, DIR, DUP, FORMAT, and other useful "recovery utilities" on as well (BUP if you use it, your favorite editor, etc.). And certainly the drivers for any other devices you may be interested in. And, of course, after putting the files on the floppy, you want to make it hardware bootable too! COPY/BOOT DY:RT11SJ DY:, for example. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817
