Did a cal on my 120c, after the cal run time went to 0

Anyone else ever see this?

I think my RTC is about to go, since the hour and date show the last day and time it was turned off.

Waiting for a programmer to capture the nvram

Did the id and options but since wowbangor has not been around I am on my own.

Trouble is no fresh 1286 ICs around.
They have not made them for years.
The ones with recent code dates are possible counterfeit..
