With modern technology at our fingertips, I wonder if there's a market for an updated version. How about storing potato mash dry mixture in a sealed chamber. When the customer presses the button, it measures a quantity and mixes the powder with water. Then extrude it continuously through a shaped nozzle and through a small quickly heated hot fat/oil frier and out through an orifice with a cutter to chop of the endless chip into random lengths. Deliver to a convenient level (perhaps for the average mouth). Add auxiliary nozzles inside the delivery tube to spot the product with salt, vinegar, sauces as pre-selected by the customer. Hmmmm. There's a fortune there waiting for somebody who can find enough idiots to buy the stuff.
