Software can be found here for the original long PCI card (non-element version); Version 1.6.1 and some later added plugins
The Element version of the PCI card does not run all the plugins and could NOT run Master X3, their premiere Multi-Band compressor for Mixing/Mastering
http://macos9lives.com/smforum/index.php/topic,1146.0.htmlAll these stock plugins run under OS9 and do NOT need challenge codes or serial numbers, the main exception to the rule was
Master X3...
Back in the day you would email TC and they would send you back a Master X3 plugin file that was "married" to your card via the cards serial number. At one point TC refused all requests for the free Master X3 under OS9 claiming "we no longer have the machine (or ability) to generate Master X3 plugins for OS9" which really sucked for those who bagged cheap cards from eBay and could not get a Master X3 plugin file for OS9. The "non-element" version of the PCI card sold for over $1000 back in the day and Master X3 was one of the selling features; I bought about 4 cards back in the day because the quality and results of the plugins were way above what was available in "Native" VST stuff, of course, Protools was a whole different topic. The original Powercore, IMO, was the "Protools of VST"
Now, to the point, as far as I know, nobody has been able to reproduce generating the Master X3 serialized file or fake the process of getting Master X3 to run under OS9; please let me know if this has changed. FYI, I have 5 to 6 unique master X3 files for Mac OS 9 and the serial number of each card associated with each file if anyone wants to reverse engineer or figure the differences in each file that corresponds to each card's serial number.
