OK, I looked at the source code to try to understand what could be the
problem. If anyone wants to download the source themselves, go to
http://handyboard.com/software/base.html and click on the link at the
bottom of the page.
The following is true of the open-source (free) version of IC. I don't
think it's changed in Newton Labs' IC, but I could be wrong.
The very first byte of battery-backed RAM, 0x8000, marks whether or not
an auto-start program is in place.
If this byte is 0, there is no auto-start program.
If this byte is 1, there is an auto-start program, and compiled code
beginning at 0x8001 is executed.
So, given this, I'd check that you can properly read and write to
location 0x8000 of your RAM.
I haven't heard of this problem before so I too am curious as to what's
going on. Definitely try things with the open-source IC that's
distributed from the HB site.

| Fred, Thanks for the info on how IC determines whether to auto-start a program or not. Based on your suggestions ---- I just finished downloading the open-source (free) version of IC.
