Sharp MZ-80 I/O (Interface Unit)

Autopsy:

I have removed two polyester capacitor (filter) that are exploded after a few seconds.

This is a I/O Extension device to connect bus-line signals being output from MZ-80K to peripheral units such as dot printer, floppy disk, colour display and so on.

    I’d just like to say a huge THANKS! for posting the pics of the circuit boards. I’ve been trying to get my hands on one of these units for years & failing every time. Hopefully, between your pictures & the rather rough copy of the service manual that I have, I will be able to build one from scratch.

    Cheers!
    Ade.
