Wow. Another Woodstock-esque "death by nicad regulation" victim.

Brilliant hack though, using a repurposed LED watch chip for a low power RTC, then decoding the seven segment outputs. I hope that guy got a raise - must have saved them a fortune.

I wonder if HP got the die from TI and packaged the chip themselves? Or if TI did it and custom marked it for them, and maybe other OEM's?

Thanks for posting - I saw that in Marc's feed and had skipped over it!
