Hi,
You can download a program to set the clock from
http://www.l8r.net/install/other/stuff/DKBInsider_II.dmsThat probably works with the Insider, since both boards use the same clock chip.
I've been disassembling the clock-setting program and it looks like the clock is mapped to memory around $B83000.
If anyone's interested in writing their own code to read/write the clock, check the
DS1216 datasheet. You could also fit a 64Kbit or 256Kbit ROM chip to the socket. Maybe an SRAM chip could go there too?
