"1 universal AA battery, Battery life: several weeks"

What a joke...

My TI-89 has that kind of batterylife but it uses four AAA-batteries.
You could call it a pda:-)(newest models even has a built in clock) but it really is a calculator with a 12Mhz 68000 and 256KB ram.

And No it won´t run AROS as nobody could get Linux to work! :-)
Apple did it right the first time, bring back the Newton!

Probably this have something to do with the unavailability of MMU in the 68000. Installing Linux on Amiga requires MMU equiped Amiga. I think you will have hard time implementing multiuser, memory protected OS without MMU. This was one of the reasons the AmigaOS wasn't built with memory protection in the first place - needs to many resources for MMUless CPUs. (68000,68010 and 68EC020).


You are right it was a memory problem, but the linux- version used was microcontroller-linux for 68000, doesn´t need a MMU. It was something about not having a big enough block of continueos memory.
