Here is what I could gather about Digital Performer 1.41Y, the version that was specifically made to work with Yamaha's CBX-D5/D3.
For some reason that I don't yet understand, I was not able to do ShrinkWrap images, so the contents of each install disk were copied into folders corresponding to each disk in the "Install Disks" folder. Please note that all the authorizations on the the "master" diskette were depleted. I have put there a folder called "invisibles" that contain four, well, invisible files... if they make it. they were used, I guess, for the authorizations, maybe.
Other stuff in this package is a copy of an installed DP 1.41Y (called appropriately "Digital Performer™ 1.41Y").
Note that this version of DP was meant to work on Mac OS 6.03 up to OS 7.5.5. If you open it in OS9.2, it will crash on you. It lacks, of course, an authorization. The other files are adjuncts to the istall, such as the Help file, the FX editor, demo files, etc..
Also included is the "MixDownCBX-D5_Demo.sea", which is a MAX 3 standalone application to control the routing and effect parameters of the CBX-D5. Probably the most interesting thing of the lot, that would be really great to have unlocked.
