Video Card

Formac ProNitron. The pictures on top of the page with the monitor are made with another graphics card. ProNitron produces too high resolution for the monitor I have. I also noticed some standard VGA monitors have also troubles with displaying the picture, but some don’t. This can be misleading as if the card was faulty, while it just needs a proper monitor.

  1. Interesting to see how different the motherboards looked on these older computers in comparison to the motherboards in modern computers today.
