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.

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.

X3.27-1978 (version 3) has a six page appendix spelling out the differences between -1969 and -1978.  From my brief perusal, the significant changes that affect our conversation look like the elimination of Record Formats V and U in the HDR2 labels.  I'm guessing there are very few version 1 tapes/tape images around.  That might be the only situation requiring resurrection of the -1969 standard.  The old RSTS 1976 doc might be good enough.
