Meanwhile, be careful not to fill up the 16M card the camera comes with 
Right. I picked up several of those in their original shrink wrap in the course of this. Also the later giant 32 cards.
I have 40something cards ranging from 256MB to 32GB all partioned to be 2GB max and Fat16 formated and made bootable. Now the oldest of the cams only take the actual 2GB and smaller cards and not even the 4GB ones but I have enough to have all I need operational at the same time.
Interestingly having remote active prevented the PC connection for chdkptp so I turned remote off. Well, maybe it was something else.
I could connect after installing the driver, could switch to rec mode, could see the live view but the user buttons to shoot failed.
JPEG said "ERROR: unsupported format"
DNG made the camera shoot but then:
