My Dad, to my eternal joy, brought home an Atari 400 back in '78 or maybe '79... probably one of the best Christmas presents ever (though he and my Mom got a ton of use out of it!) I still have an Atari 130XE connected to my main TV.
My wife's old Canon AE-1 is on our "camera shelf" along with the usual 50mm lens... but we're not real proud about a lowly Canon sharing shelf space with the other cameras.
Sears used to sell a rebadged Pentax SLR under their own name... I'm not sure if they had other brands, also. You do still see Sears-branded Pentax-mount lens come up for sale fairly regularly on eBay and elsewhere. I have none in my collection though and I don't think there was anywhere particularly exciting so it'll probably stay that way.
