JAmerican,
I just thought of something, and I don't know if this has been mentioned to you.
About these 3 models C1000/C3000/C3100.
The C1000 and C3100 are similar in this area. They both have 128mb of flash memory.
The C3000 only has 16mb of flash.
When you're considering the different ROMs, the C3000 has issues because the flash area is so small.
There are DIFFERENT versions of Cacko and pdaxrom for the C3000.
These were developed later, (after versions for the C1000/C3100)
The C3000 stores the bootloader in flash, and it's ROM on the first or second partition of the microdrive.
(If I'm wrong on this, someone please step in and correct me).
The C3000 and C31000 both have a 4gb microdrive. (It's actually another CF slot, mounted internally).
Some people actually open their Zaurus and swap the microdrive with a bigger CF card.
The C1000 has no internal microdrive. The C1000 also doesn't have the internal CF slot.
There are also some chips missing, (that have to do with the CF slot in the C3000/C3100).
You cannot put a microdrive inside a C1000, as said above, parts are missing.
(You could try to solder in the necessory parts, but it would be more economical to get a different model).
But, in my opinion, when it comes to trying/using the various ROMs, you're better off choosing a C1000 or C3100,
(or a C3200), because of the flash memory size.
