A couple of problems have popped up. One is PSU related. My A1000 does not like powering everything I want to run:
One external floppy (CA 880 - I think)
Commodore 256K RAM expansion
Starboard 2 w/2Mb RAM
DKB Insider 1Mb version
I don't seem to able to find a new, more powerful PSU that will fit in the case. I would love an idea or two on this...
Another, not so important issue - The Insider has a battery backed clock on it. Where have they hidden the battery?! Am I really going blind?

Your power supply more than likely needs to be "rebuilt". All this entails is replacing the electrolytic caps and maybe a bridge rectifier (but I seriously doubt the latter).
Also, try making sure all the grounds are good from the daughterboard to the external bus back to the power supply. Lots of docs out there re: A1000's grounding...

If it is like the Spirit, its a big black "square" in the corner of the board (in the below picture, it is top left corner/opposite CPU). Inside that "block" is a coin style battery. To replace it, you will have to use a dremal to cut it open. Best bet is to get the 2 contacts instead that come from the battery and solder a new one one. There is a complete "step by Step" somewhere, but google is not being co-operative right now. it could even be in the photo's here.

Because of several projects that are going in my A1000, there just isn't room for the DKB InSider. I may hate myself in the near future, but I am putting this board on eBay at:

I think I have started it at a very fair price.
It's a shame there isn't a little more room in this case - But I think this is the best looking Amiga case there is.

From the specs sheet (http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2638):
"The DS1216 SmartWatch RAM and SmartWatch ROM sockets are 600-mil-wide DIP sockets with a built-in CMOS watch function, an NV RAM controller circuit, and an embedded lithium energy source."
Pretty surprising at that size.
