This is the
latest for braille production. The perkins is the main brailler in use, itÕs
a purely mechanical ÒtypewriterÓ designed in the 40s and production started
in the 50s. Basically unchanged. It weighs in at about 6kilos, imagine a
grade one child trying to lug this around school. Mountbatten made the
mistake of attempting to be all things to everyone. Stores docs in static
ram so very limited space, old
8 bit processor slow, power hungry and unreliable, I know I used to fix
them. Huge lead acid battery so very heavy and noisy. Multiple Òblack boxesÓ
hang off to connect printers and peripherals.. Jotadot is a new manual
device.
