i'm searching for a pc104-board with battery backed SRAM or something similar. My problem is that a customer is building machines with an linux-powered SBC, which is collecting data over 10 serial lines (another pc104 board) and storing them to a harddisc. So far so good, but the users of these machines cannot be argued to NOT switch off these machines without shutting them down correctly. So we have always data loss, which we want to avoid.
So now we want to put all the data into these battery backed ram and write it in cycles to the harddisc. But we cannot find such a board. Anybody has an idea?
Thanks in advance, Jens
