SEIKO RC-4000 PC Datagraph Very Rare 80's Vintage Computer Watch NEW in the Box

  

A real gem for Vintage Digital Watch collectors, includes original box, software, cables & instructions! The PC Datagraph was the worlds smallest computer terminal when launched in 1985.

The display is a three-line dot-matrix display with 2 lines for data and one larger line for the time. The watch has 2k of storage which held 80 pages of 2 x 12 characters and can be divided into sub-categories each with their own label.

With a Cable & Software Set, it could communicate with popular computers of the day like the IBM PC, Commodore 64, Apple II, II+, IIc and IIe and in the UK the BBC-B and Sinclair Spectrum using a cable and software (not included). There is a small RS-232C serial port on the left side of the watch and a plastic clip attached to the watch to allow a cable to be plugged into the serial port on the computer. The Wrist Terminal Data Manager program allowed you to upload and edit your data. You can input and edit data directly on the watch, using the buttons and a cursor. RC-4000 series watches were so useful at the time that NASA gave them to the astronauts on the Space Shuttle "Atlantis" on Mission STS-43 in 1991, which allowed them to connect to a Macintosh computer and communicate with Mission Control via a Fax Modem, so they could send information and reminder alarms.
