Pandora's box is a video processing peripheral for a workstation or PC. This document describes the model of Pandora's internal workings which is exposed to this host computer. The host sends requests to Pandora, and receives a reply to each one before sending the next request. Pandora can send
asynchronous events to the host independently of these request-reply interactions. Pandora and the host can also asynchronously exchange data such as bit-map images and digitised audio.

(Pandora may not be a silver bullet for prior art, but it does show what experts in the field were doing at the time, which goes towards nonobviousness.)

Voice Messaging (1977 - 1978)

In 1977-78, an experimental system in which "voice messages" were transmitted from an originating packet voice terminal in the form of live, compressed, packet audio over the ARPAnet to a storage system at CCA. The audio was stored in compressed form. These voice messages could be later be retrieved by the intended recipient connecting to the storage system and requesting real-time playback of the stored audio across the ARPAnet to the recipient's packet voice terminal. The packet voice terminal was based on a PDP11 minicomputer; the personal computers of that era were 8080's with quite limited capabilities.
