I need to find a way to open and print a large number of CAD files generated in the late 90s (mostly 1998) with a CAD system called CAD-Pack. I was told it was related to CADAM, but I am unfamiliar with any such CAD tool. I have performed repeated web searches for CAD-Pack and I've visited the CADAM web site, but I am only finding dead ends.
If you open the files with a text editor, you can't read most of the data but each file has the following text in the first line:
PCADT CAD-PACK REV 5.00CAD-PACK
Any suggestions for opening/printing these files would be greatly appreciated. Unfortunately, our client only has hard copies for a small subset of these drawings.
