[OZAPRS] New Proposed APRS Digi for Adelaide - ideas?

[Marcus B]

If you want to lengthen the life of the SD card, it's easy enough to set up
a pi with a read only filesystem, and I tend to use a class 4 card, but
that was an issue with the pi1's.

Personally I've never had an SD card fail in a raspberry pi, even on my
overclock pi1's that we notorious for failing.
