Psion Series 3c
The Psion Series 3c was the next variant after the Psion Series 3a. (A Psion Series 3b does not exist). It has a slightly different external appearance to the earlier variants because a redesigned badge is placed centrally on the lid, the lid has fewer undulations, and a port for an infrared connection is visible. The plastic case is painted matte dark grey. The backup battery for the Series 3c is a CR1620.
The Series 3c, and the later 3mx, have an Easter Egg. In the System Screen, if you display the "About" screen, then type:
!Mrs T Bogan!
the English anthem "Jerusalem" is played, followed by a list of credits. (It is a one-shot affair; if you mis-type, you need to kill/restart the System Screen with Ctrl+Psion+Shift+K before you can retry.)

Famous quotes containing the word series:
“I look on trade and every mechanical craft as education also. But let me discriminate what is precious herein. There is in each of these works an act of invention, an intellectual step, or short series of steps taken; that act or step is the spiritual act; all the rest is mere repetition of the same a thousand times.”
—Ralph Waldo Emerson (1803–1882)
