I always thought that the Maytag Reverse Rack was the most innovative design, when I was growing up in the 70's. Just the fact that you could put tall items in both racks.
I had a group of friends on my street, in the mid-70's, we used to hang out at one the kids house. His parents had the Golden Harvest trifecta ( Maytag washer A606, Dryer D606 and the portable dishwasher WC400 ) Whenever I had a chance to be alone in the kitchen, where all the appliances were, I opened the door of the dishwasher and marveled at that racking system.
At my house, we had the GE Potscrubber. A good dishwasher, but I found the racks so flimsy looking.
Later on, when I moved out to my own place, I got a vintage Top Loading Inglis dishwasher, in coppertone. A year later, an avocado green WC401 pops up in the window of the used appliance store, next to my appartment. I went in, and bought it on the spot. My life dream was now fullfilled. I had to let it go 8 years later, when we bought house, and everyone told me you can't put an old dishwasher in a new house.
I still miss that machine. But I've been doing well with my Bosch dishwasher.
