[OLPC-devel] Keyboard to CN23

[Mark J. Foster]

Hi, Folks!

Please note: Earlier on this list, Ray Tseng, the head of firmware for 
OLPC at Quanta, mentioned that they had to temporarily disable PS/2 
support in the Insyde BIOS due to keyboard/mouse conflicts with Insyde's 
buggy USB support. If you're going the PS/2 route, I suspect that you'll 
need to use LinuxBIOS.

With that caveat in mind, I've asked Quanta to supply a manufacturer and 
part number for the male connector that plugs into CN23.

FYI!
