The Macintosh IIsi Uses a 120/240V AC Power Supply. It provides power directly to the logic board. From there, it is distributed to the rest of the computer.

This drive was manufactured by Sony in 1990.
Excellent pictures and easy guide! Thank you very much. My IISI floppy drive started flawlessly after 25y and the disk could be read. however it did it just once. Then I could not eject it any more. It did not work anymore. Can I replace it with a Sony MPF 920E? What type of cableadapter do I need
Generally these old Macs only work with Apple style floppy drives, they use both a different cable and signaling standard than PC drives. If your drive isn't ejecting your best bet is to either replace it with a similar 1.44MB "SuperDrive", or service the drive. There are some good videos floating around the web about how to repair and maintain these old drives, and it isn't actually too hard to disassemble and clean them.

The fan recieves power from two contacts on the logic board and has no connector.

In all of the years that I have worked on this machine, I have found no good way to remove the fan.
-
The best way to start, is to push in here on the side of the fan.

Being careful not to exert too much force, try to push in, and wiggle the fan outward as such. (2nd Photo)

You can now lift the fan all the way out, and remove it.

The Fan Power Contacts on the Logic Board:
There is no need to pull out the fan. Just take a knife and you can squeeze the tab in step 7
I wanted to second what Willy said; as far as I can tell one is intended to remove the PSU before the fan. You just jam something the right width in between so the PSU tab is depressed, pull it out, and after the PSU is out removing the fan is easy.

To remove the power supply, squeeze these two tabs and lift the front up.

On the back of the power supply, there is a tab that also must be pressed to remove the power supply fully. You can then lift it out all the way. A firm tug may be necessary to seperate the power connector.
