HP 48G - what next?

[JSS]

Hello again,

I don't have the understanding about 50G 's communications capabilities and have a lot of open questions. Hope I can solve these issues before my 50G arrives.

1) Anyone knows about the 50G 's non-standard RS232 low voltage level serial port? A special cable which includes low voltage level driver electronics is needed, but does someone still sell them?

2) 50G 's USB port, is it fully standardized (e.g. USB1.0 & normal voltage levels) and supports similar functionality than using the serial cable connection?

3) Finally, about max 1 GB SD memory cards, they state that 50G supports FAT32 only partially and is restricted to max 1GB, but does it accept larger memory cards if formatted into 1GB partitions?

Thank you again for your answers.
