These are scans of the Doramitchi original Japanese instruction manual.
Note: when you click a link, an image will appear scaled to fit your screen. If you move your mouse over the image, the mouse pointer should change into a magnifying glass with a plus (+) in it. (If it does not, click the image first, or press F5.) When it's as such, click the image to see it full size. These images have been scanned at 200 dpi, which make it quite easy to see all the details.
