I hope someone has written something in the public domain. Digital's EXCHANGE does not, in fact, know the format. I don't have any utility to do it; I am responding primarily to copy your message to `info-pdp@sei.cmu.edu'. The current RSTS/E disk structure is known as RDS1 (not to be confused with RSX's and VMS's odious one--oops, ODS1) :-} No other operating system uses RDS. Get ahold of Mike Mayfield's _RSTS/E Monitor Internals_ if you end up writing a utility yourself. It describes the layout of RDS1 (and also RDS0, the structure used by pre-V8.0 RSTS/E systems). But since you're probably converting only one disk, it would probably be faster and simpler to find a friendly RSTS/E site with RL02's! ---- Ed McGuire, Systems Coordinator, Grinnell College, MCGUIRE@GRIN2.BITNET P.S. If the disk you're reading is RDS0, I think I have a utility written on RSTS/E to read it . . . the RSTS/E I/O would need to be changed to QIOW calls, but it might be more or less straightforward.
