Sir Mark Rawlings as the first member to correctly give the Applied Concepts Boris Diplomat released for sale in April 1979 Kudos to Clive Munro for also getting the right answer officially called the BDI ,this was the worlds first truly portable chess computer as it was both a hand held unit and worked on batteries while there is a fair amount of information available on the net regarding the BDI ,i dont think there is any site which specifically mentions it as being the very first portable(or at least i could find no such information) there were several very good answers ,however the computers mentioned either were released for sale after the BDI or if released earlier, did not run on batteries and therefore are not true portables soon after the release of the BDI Applied Concepts released the BDII the only difference being the color(Brown as opposed to Blue for the BD1).on the BD II box the claim of worlds first battery operated portable is proudly displayed the program was written by the team of Slate and Atkins and contained a whopping 3K of ROM somewhat unusual for a computer then and now, and perhaps even a bit ahead of its time, there were no pre- set levels of play rather the computer had a 100 hour timer and the user could program the computer to calculate its move from instantaneous to up to 99Hours 99 Minutes and 99 Seconds..(although this latter level seems a bit impractical considering the batteries would probably die out well before) The Worlds First Portable Chess Computer : http://pg.photos.yahoo.com/ph/cpaa2@sbcglobal.net/detail?.dir=c0f3&.dnm=11d6.jpg&.src=ph Best Regards Steve
