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.
I think, but this is a *very* vague memory, that one of the later additions was
the addition of the century number to the date fields. Originally, ANSI labels
were not Y2K compliant.
I think that is correct. RSX handles years past 1999 on ANSI tapes. And
I remember that one additional digit was allocated for that use which I
think was just a space or something before.
