I asked our (Intel's) corporate librarians to see if they could find X3.27-xxx and in particular -1969 (the original) and -1978 which was version 3. I agree with Paul, that V3 (-1978) was the version that most people implemented. I seems to remember that, VMS started with V2 and upgraded to 3 - as I remember on VAX Serial #1 trying to read tapes from it on the 360 or the Univac was funky.
I wish I could remember what changed between the versions. I once knew, and I've sent a note to one of my old housemates that wrote some of the VMS tape support years ago. He might remember/have some of this stuff. Anyway, I'm trying to find my old copies the documents, but I fear they might have been lost in the apt flood of a few years ago (I lost some historical stuff in that that my wife made to toss). At one time, I had a photocopy of the -1969 with my IBM/360 files. I know I still have one of the best document on using tapes CMUs Computer Center wrote in the early 1960s (I know I do still have it because I found that and referred to it last summer). Anyway, I'll keep looking this weekend. BTW: the current version of the spec is not ANSI X3 mumble... It's now called: INCITS 27-1987 [S2008] http://webstore.ansi.org/RecordDetail.aspx?sku=INCITS+27-1987%5bS2008%5d It's $60 from ANSI Clem On Fri, Jan 8, 2016 at 11:51 AM, Paul Koning <paulkon...@comcast.net> wrote: > > > On Jan 8, 2016, at 11:19 AM, khandy21yo <khandy2...@gmail.com> wrote: > > > > > > The programming manual that I foubd for rsrs.e documents it as 1. > > Thats the only documentation I have for the format, so went with what I > had, and compared it against rsts distribution tapes.
