It’s been a long time but I *think* the ET4000-based card recommended for the PT68K-4 board was made by Oak Technology.  I had a more generic one that was a lot cheaper and it worked ok for me.

By the way, have you actually spoken with Fred Brown recently? I would love to get his email to perhaps pick his brain on a couple of things concerning my PT68K-4 which is missing a few things for it to boot OS9.
