I just put an R129 Information Access CD up for sale on ebay.
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=537829992
This disk is from a MB dealer mechanics training program of some kind. (anybody but me ever see these things?)
It's NOT a service disk. It doesn't contain procedures to get your hands dirty. BUT, it does cover every subsystem in the car, including body, chassis, suspension, engine, tranny, electrical etc.
All told, I have 10 disks: 129, 163, 170, 202, 203, 208, 210, 215, 220 and SRS (1984-2000).
If anybody is interested contact me off-list cth@mbz.org
