I had a circa '85 TOL KitchenAid which looked quite a bit like this one, although I don't remember quite that many pushbuttons. I think mine was a Hobart-based machine, as it heated the water before the first wash began, and had the classic Soak and Scrub cycle behaviors.
I also believe someone told me that my machine was probably one of the last of the Hobart crop. This one looks a year or two newer than the one I had, so I'm going to vote that it's Whirlpool-based.
Hopefully, one of the KitchenAid dishwasher experts will weigh in and give you a more solid answer. And while you're here, KA expert, can you confirm that my machine was a Hobart? Sorry, but I don't remember the model number. I'm trying to remember when I purchased it---I think it was shortly after my mom passed away in April of '85. That was SO many brain cells ago, LOL.
