Yep, that sounds about right, at least on the data formats. A survey now is gathering orders of magnitude more data than it would have in the 80s (especially 3d

Yep, that sounds about right, at least on the data formats. A survey now is gathering orders of magnitude more data than it would have in the 80s (especially 3d/4d surveys), but I guess the formats didn't really need to change. I don't miss writing code to guess whether a file has traces encoded in IBM floating point or IEEE; or handling SEG-Y headers which ought to be EBCDIC but are sometimes ASCII :-)
