I have an SL-5500. I also have an old Casio Cassiopeia. The AC adaptors for these two machines are essentially identical, and I have been successfully using the C's adaptor in my 5500 for a week or two.
My question is this: The Cassiopeia came with an external battery pack which plugs into the AC adaptor plug. Could I use the external battery pack with my Zaurus?
It seems like I should be able to, but I thought I'd see if there were any caveats. I sure don't want to fry my power supply! The battery pack consists of two 2V/2A (I assume that means "two volt, two amp") batteries, if that tells anyone anything.
