I've just been going through a friend's collection of service fiche for him, culling out his outdated films (I'm a nice guy, this is tedious work). There's something about his diagnostic fiche I don't understand.

Perhaps he's sloppy, but he can't be this sloppy. Benz seems to have shipped lots and lots of updates to the diagnostics fiche. He latest is revision 79, dated 8/97 (see attached photo). He also has revisions 78, 75, 74, and dozens of others.

The vast majority are like this photo, missing a film #1. From 1986 to 97, he has two dozen sets of these films, and only one has a film #1. In fact, it has two, a "Diagnostics Directory 1" and a "1A".

Those two films cover groups 01-98, as do the films 2-5. I presume that these two films are sort of a master index, and the other films are the details. And, like all the other updated microfiche throught the system, the 2-5 pages have been updated often, while the films 1/1A have been updated rarely.

Sound about right?

Also, if anybody has the nicely formatted memo from Mercedes that lists the complete set of films available as-of 1995, 96, 97 or 98, I'd love a xerox of it. I have them for earlier film sets. It would make my cataloging this fiche a heck of a lot simpler.

Thanks. -CTH
