In front of the keyboard it has a 40-line Braille row with an integrated OSP (optical sensor pointer=which should act like a mice).
Left and right of it there each three small buttons which are called "display buttons" and are used for window and cursor control.
Right of it there are another four trigger buttons which are the so called "INKA-buttons" which are used for system functions.
Outer left and outer right of the whole keyboard are another two vertical OSP rows with each 27 optical sensors and which allow you to find out about current display structure or just "scrolling" vertically the braille row in the front.
Also the status "led's" are not missing. These are the three notches above the numpad. However as LED's obviously dont work for blind people, these are three metal sticks who got pushed up by a magnet to signal. (num lock, caps lock, scroll lock)
On the back it has connections for a separate power supply, an "ethernet look like" (RJ45?) connection for the keyboard cable and a serial connection (COM1/COM2) which also can be used for connection to the pc.
dat logo! and now look at our stickers.
Some closeup.
Mx clears and spacebar is mx grey.
Caps are cherry doubleshots white on black. Typically for blind-stuff they have these nipples on certain keys. And these are actually little rounded metal bolts which are pushed through the cap. (yes, these were times where things were done properly
)
pcb or engine?
