Thanks again for your support,
I believe you are a great expert of these old editing system.
I just love the simplicity and truly plug and play of Cinewave on MacOS, got it working flawlessly on G4 and even G5 Power Macs. Why T3K on Windows is a nightmare? However I already tested the two board on an older Dual Pentium 3 workstation, under Win2k , I had same issues. Everything installed, Targa self tests Ok, but as I launch Premiere, after some loading, there is a freeze.
I purchased these 2 boards on ebay, many years ago. As I got them , I tested and it wasn’t a success. Then I “archived” the boards. Just recently , as I re-finded them (i check periodically my older stuff), I wanted to give a new chance, but I had not luck again.
