Title: DKB Insider 1000
Post by: kernal on November 15, 2007, 08:17:05 PM

Hello All,

I just recently aquired a DKB Insider 1000 memory expansion for my A1000, which works great. The only problem is that it has a Battery Backed clock onboard, and is enabled through software, but I don't have the disk that would have origionally come with the hardware.

Is there any chance any of you user have the disk that I could download.

Thanks

If you find the disk let me know as I have this card as well.  Isn't the battery dead by now though?  I cannot remember what kind it is though, or if it can be replaced.

Let me know if you find the disk and if the battery can be changed.  Cheers

Well, I checked it out... the unit is a Dallas DS1216 integraged clock system with an integrated Lithium battery. You can still get these units, but it would require a desolder and resolder on the Insider circuit board. Not worth the effort I assume.

I would still like the disk though, because I think it has some other utilities on it as well.

Hey guys, I'm not sure if the Battery/Clock thingy looks like the ones on Sun machines, but if it does, then you can try removing the lithium "half" and adding a lithium coin battery. I've done it on my Suns and it's quite easy if you have some modest soldering skills. Check it out:

Good luck!

Hi,

You can download a program to set the clock from
http://www.l8r.net/install/other/stuff/DKBInsider_II.dms (http://www.l8r.net/install/other/stuff/DKBInsider_II.dms)

That 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 (http://www.maxim-ic.com/getds.cfm?qv_pk=2638). You could also fit a 64Kbit or 256Kbit ROM chip to the socket. Maybe an SRAM chip could go there too?
