Editing Hatsucoh Electronics HEKB01 (section)

==Release Date==
While the EM486 was released in 1995, the HEKB01 pictured below has a PCB and Plate stamp with a '0' which would indicate either 1990 or 2000<ref name="realforce_date">[http://deskthority.net/wiki/Realforce#Manufacturing_Dates Realforce Manufacturing Dates]</ref>. There are three suggested reasons for this; 1. It's possible that Topre re-used an old PCB and mounting plate for this keyboard, as Hatsucoh Electronics also did release a data entry machine in 1990. 2. Hatsucoh continued making EM486 keyboards up until 2000 and perhaps beyond. 3. The date stamp format is different for this board.
