Here are some images of my own TR-808. I got it cheap because of the one button missing and no midi. I could not live with it looking like it did so I ordered a Jupiter-8 kit from chipforbrains of eBay and got one of thse programming buttons.

One of the programming buttons are missing, although it worked it didn´t look all that nice IMO.

The TR-808 is a nightmare to get into, thousands of screws everywhere.

After an hour or so soldering and putting it back together it finaly looks like new again. Thanks to chipforbrains on eBay for providing remade parts !
