Boysenberry in Bureaucracy

[hygraed]

I'm playing through Infocom's Bureaucracy by Douglas Adams again, and I've got a question about the "Boysenberry" portable computer possessed by the player character. I had always assumed that the name Boysenberry was a play on the Blackberry PDA, until I realized that the Blackberry was introduced twelve years after the game was released. Was the name "Boysenberry" a remarkable bit of prescience on Adams' part, or was there a previous incarnation of the Blackberry device that was around in the late eighties?

Apple = fruit.

Boysenberry = fruit.
