IIfx motherboard uses two 3.6V batteries and the machine will not start without them – it turns the power supply on by providing a battery voltage on one of the power supply pins.

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.

DaynaPORT E/II-3

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

I have a dead IIfx thanks to a double battery leak. Patiently waiting for a donor to appear on ebay. One day.
