Kazunori Minatani <minatani@debian.or.jp>, who is blind man and good
hacker, and I have developed Debian customized CD-image for blinders.
Unfortunately, this is based on potato and has no good documentations,
but it will be helpful for blind people who use serial console or USB
pin display.

You can get from:
http://misato.debian.or.jp/~kmuto/minatani-uhci.iso (USB-UHCI support CD-img)
http://misato.debian.or.jp/~kmuto/minatani-uhci/ (USB-UHCI support FD-img)
http://misato.debian.or.jp/~kmuto/minatani-ohci.iso (USB-OHCI support CD-img)
http://misato.debian.or.jp/~kmuto/minatani-ohci/ (USB-OHCI support FD-img)
(But misato.debian.or.jp will be discarded in the future...)

* RS232C serial console support. (When first boot prompt is displayed,
  just type like 'linux console=ttyS0')
* brltty engine embedded. (You can use USB or serial PIN display.
  When first boot prompt is displayed, type 'linux braille-device=?
  braille-driver=? speech-driver=? dot-translation=?')

  braille-device: device name. (ttyS0(default), ttyS1, ttyUSB0, ...)
  braille-driver: brltty driver name. (al(Alva, default),
    bl(BrailleLite18/40), cb(Tieman CombiBraille), ec(EcoBraille),
    eu(EuroBraille), md(MDV braille), ts(TSI), va(BAUM Vario))
  speech-driver: speech driver name. (no(No speech, default),
    al(Alva), bl(BrailleLite), cb(Tieman CombiBraille), fv(Festival),
    gs(Generic Say), tv(Televox))
  dot-translation: translation language (es, french, german, it, no-h,
    no-p, simple, sweden, swedish, uk, us(default))

  (Installer beeps when root disk loaded and launched up brltty)
* GNU Parted in /tools/ directory.
* This image only includes installer, so you must need to get Debian
  packages via official CD or network.

Known bug:
* Installer doesn't care about boot parameter for brltty. You must
  write same parameter in lilo.conf or specify parameter on boot prompt.
* This image use kernel 2.4.*, but potato installer can't handle this
  module location type. You can't setup module on installer. Please
  use 'insmod' on shell or upgrade woody/sid.

Good. If someone create devel-ML for blind people, Minatani and I will
join it.
We can provide all of our know-how.
I wrote a documentation about our image at
http://www.topstudio.co.jp/~kmuto/debian/column/brltty.html in Japanese.
