Cortex Personal Access Device

A transparent scan of the prop, a Cortex Personal Access Device (CPAD), used by Alliance agent and lawman Laurence Dobson, in the first episode, "Serenity" of Firefly. Interestingly enough, the screen is entirely nonfunctional, the active Cortex screen seen was added in post-production. The prop itself is actually comprised of two (rare, obsolete) personal organizer devices, the Franklin RF 8110 Rolodex and Fellowes Type 'N' Go PDA/Organizer.
