Motherboard






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.
Memory



ROM


Power Supply
CR-45S










Floppy Disk Drive
1.4MB Sony MP-F75W-11G



Hard Disk Drive
122MB Conner CP30100



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.


Network Card
DaynaPORT E/II-3


Video Capture Card
SuperMac Spigot NuBus


Capacitors List
Covers both the motherboard and power supply.

Reassembly








Some Dirt



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.
