|HP 15C LE firmware and memory questions|
Message #1 Posted by Lode on 27 Jan 2012, 3:13 p.m.
I've got some questions about the HP 15C LE.
Would the HP 15C LE work exactly like a HP 12C LE (except for the labels on the buttons) if you put the firmware of the HP 12C LE on it? Or are there some internal differences?
Since it's an ARM CPU emulating a NUT CPU (afaik), which firmware can you change: only the NUT firmware, or can you change the whole firmware including the NUT emulator part, and e.g. create a firmware that just uses the ARM CPU directly to do stuff?
Does it really only have as little memory as the HP 15C had, or does it in fact have a lot more memory in it, for example to run the emulator, but it's just not accessible since the emulated HP 15C firmware isn't aware of its exixtance? Does a chip of 500 bytes of memory (or how much was it?) even exist today? How much physical memory is in there?
How large is the chance that there'll be released a bugfixed version of the HP 15C LE firmware, e.g. fixing the weird screen flashes that happen if you hold down "SST", the high battery drain when holding down a button, etc...?
Thanks a lot!
