ALL my Kenmores except for one got sent away. The Catalyst is about to get a refresh.
The triple dispenser system was let go for the non-lady Kenmore and non-Electronic sets about when Kenmore went with the curvier console design and changed the Kenmore logo to that horizon-curve-swish thing, about 1995-1996 or so. I think the 90 series comes from the "quiet pak", 3 speed motor, intermittent agitate, and one or two extra cycles that the 80 series does not have. I had the same machine, just not with the temp degrees written on the console.
