My ATS-803 / DX440 no longer powers on, after a power failure

Is there a reset hole? I haven't looked closely but maybe somebody
knows.

It's on the AC adapter, and the 2 AA's keeping the internals running
are okay.

It's been powered on continuously pretty much for 25 years.

25 years? Are they *that* old?

Anyways, I've reset mine in the past by removing the batteries for an hour
or so.
