The special Autodesk 3ds Max 20th Anniversary site is now live on the Autodesk AREA community:  
http://www.the-area.com/maxturns20

Please wear your 3ds Max & 3D Studio memorabilia (t-shirts, hats, etc.) to SIGGRAPH in order to receive a free 20^th Anniversary t-shirt.  Those not attending SIGGRAPH can order a t-shirt at the 20^th Anniversary online store: http://www.zazzle.com/autodesk

I started with 3D Studio R4 DOS, but also have an original 3D Studio Release 1 package complete with 7 - 5.25 floppies (working).

Next year 3ds Max turns 21, so in the US it can legally go celebrate with a beer.
Congratulations 3ds Max Team!
