I see that the HP50G only supports original SD cards up to 2GB?
What are the requirements? Original plain SD, ie not SDHC etc?
I'm not sure where to find one - can I use MicroSD? Is that just a packaging difference?

Transfer speed doesn't really matter but card startup time has a
noticeable impact because the 50G powers down the card after every operation, to save battery.
When the 50G powers up with an SD card inserted, it works out how much
free space there is by counting clusters. The more clusters there are
the longer the boot delay. So format as FAT16 as that is limited to
65536 clusters. If the card is large then it may help to partition the
card into two volumes: a FAT16, 128MB first volume and FAT32 for the remainder as a second volume. The second volume won't show on the calc
but you can see and use it in Windows.

I use a super-old 16 MB SD card from one even older camera :-)
Formatted as FAT16 works very well, everything I need fits on it.
Just using the opportunity to say hi: "Hi!" :-)
glad to see the group stil exists...
I guess we just ran out of subjects for the time being :-)

Hi. We'd have more to discuss if HP would release a new version of the
50G up-to-date hardware. :-)
