My employer is cleaning out its old storage rooms and just handed me a new/old toy!
In fact, this is the very unit carried up Mt. Everest by our ill-fated expedition a few years back.
With some help, I may be able to jury rig this thing for SMS style email and tracking for the boat!
(Of course, the service side may be prohibitive in cost, in which case I will just hack it for the hell of it and see what I can make it do.)
