I think it's more mid 90s.
It has the older Kenmore logo and in 1996 they switched to the swoosh Kenmore logo, which I believe was also when they changed to the curvy white consoles with the rubbery gray and white knobs. All of those style consoles were white that I've seen.
During the late 80s/early 90s they did have this boxier style console available in white on white (usually higher end models I think), but most were black/woodgrain. That all black style seems unusual though, I don't recall seeing it.
