I've a sneaking suspicion the same chip is used on the old HTEC Kitty 
Card 8051 board (as sold by Greenweld many moons ago, back when they 
weren't an Innovations Catalogue knockoff). Catch is, I can't find the 
circuit diagram to confirm this -- it's either on the LAN share, or one 
of the hot-swap SATA drives. So that's four different places to look...

If it turns out they do use the same chip, I've got four of them stashed 
in a box under my workbench -- I might be persuaded to part with a board 
or RTC chip, but as I recall they aren't socketed, so removing one 
intact might be a bit tricky.
