Although not a "repair" item, this may be useful for Macintosh users...
According to MB, the repair/service CD-ROM will not be Macintosh compatible.
Just bought one of the remaining body/chassis manuals and will have to figure out what to do for engine repair information.
No, this is not intended to start a lengthy B.S. session on Windows vs. Mac OS.
It's just that there are plenty of Macintosh fans who happen to appreciate and maintain MB and don't want to have to use Windows emulators.

What engine manual are you in need of? I have some old manuals in my library that are going to be replaced by CDs as they become ready.

Wow !
What a speedy response.
Thanks.

I am very anxious to locate an engine manual for 617.951 (?).
1981 300SD.
Not sure of other manuals besides this one and the body/chassis manual.

Thanks again.

(I just posted another msg concerning timing chain replacement, before you sent me your msg.)
