Original Description:
SEIKO RC-4000 PC Datagraph Watch [COLLECTORS ITEM]A real gem for Vintage Digital Watch collectors,  Includes pristine original box, software, cables & instructions!This is a BRAND NEW and completely unused item, so it is in showroom condition The PC Datagraph wasthe world’s smallest computer terminal when launched in 1985. The display is athree-line dot-matrix display with 2 lines for data and one larger line for thetime.   The watch has 2k of storag...e which held 80 “pages”of 2 x 12 characters and can be divided into sub-categories each with their ownlabel.  The default was 5 categories,  each with 15 "pages" of data (3 x Memo, 1 xSchedule Alarm and 1 x Weekly Alarm) . However it can be re-programmed from software and increased up to 12 categories or reduced to 1 category within the maximum of 80 "pages" in total.  (EG. you could have an alarm category with 79 alarms each with a 24 character message).With a Cable & Software Set, it could communicate with popular computers of the day like the IBM PC, Commodore 64, AppleII, II+, IIc and IIe and in the UK the BBC-B and Sinclair Spectrum using acable and software (not included). There is a small RS-232C serial port on the left side ofthe watch and a plastic clip attached to the watch to allow a cable to be pluggedinto the serial port on the computer. The Wrist Terminal Data Manager program allowed you to upload and edit your data.  Included is a copy of the IBM PC software, but it may only run on older computers or may be possible with an emulator and USB to Serial converter.  There is a newer version of software written by a user that I have tested and I can pass contact details if required.Youcan input and edit data directly on the watch, using the buttons and acursor.Aunique feature of these watches is that they could also transmit their data backto the computer using the optional RC-4200 adaptor (Not included) so you could update yourcomputer after editing.  This made it theWORLDS FIRST watch with 2-Way data communication!They could also communicate with other RC-4000 series watches using the optional RC-4300 Wrist Adaptor (Not included) Another World First?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.I have included some images of brochures of the RC-4000 Series in the listing, to give a better explanation of the watch functions. (These are not included) The following text is also from the RC-4000 brochure............The Complete PersonalData SystemTheRC4000 is a handsome and fashionable high quality product just as you would expectfrom Seiko. But it's a great deal more than just a watch.  You can enter virtually any type ofinformation into the RC4000 and take it wherever you go. You can enterappointments, notes, price lists, telephone numbers, thousands of bits of usefulinformation, all conveniently organised into up to 12 data files. And you canset the powerful reminder alarms for anything up to a year in advance. Data can be uploaded or downloaded viamost of today's most popular micro-computers through the RS232 interface orentered directly into the RC4000 itself.  It could even be transmitted directly fromanother RC4000 using the RC-4300 Wrist Adapter (not included).To recall data you simply press a buttonand read the clear dot matrix display. To update you can either use the RC4000alone or your micro. Data can then be saved for future use or printed out. Both wrist and pocket models areavailable along with specially formatted software to make data entry simple.  Until you've used it you'd never believeyou could carry so much useful information around with so little trouble. Onceyou've tried it, you'll never want to be without it!
