Re: Repurposing the HP39GII? Message #10 Posted by Han on 2 Oct 2012, 10:39 p.m., in response to message #5 by Eric Smith
Oh I think I may have misunderstood "SDK" then. I was thinking an SDK kit would basically include the source to the current ROM, and various compilers/linkers and documentation for the current hardware. At $12,000 it appears you probably also get tech support and possibly even hardware for testing.
Since the chip is an ARM chip, I wonder how much we could probably figure out just from opening up the calculator and comparing what we see with the chip datasheet (address lines, data lines, etc)... somewhat like what was done during the hp49g+ emulation days.
As for a compiler, any decent ARM compiler should get us through some of the basics. Maybe I'll have to invest in an HP39GII to open up.
Edit: oh I just realized you said the datasheets are not available =(
