I recently acquired a PT68K-5 boardset from Frederic Brown (Peripheral Technology) and need to get a proper ISA VGA card.
Anyone have one of these systems that can tell me exactly which card you have? Should be a Tseng Labs ET4000-based card, but all the ones I have only partially
work properly. It's not defects, but compatibility, and engineering changes that came along with the video cards.
I'm hoping to find someone who has a working or previously working setup with G-Windows, so I can try to get the same card.

Thanks, and cheers!
