[Olpc-za] Fix clock problem

[Henk Boshoff]

Hi,

I'm impressed by the size of the battery....

The only piece of information I can give you is that it might be due to 
the Nokia built in security. Nokia usually has some proprietory stuff 
built into their cables, to prevent people from using standard cables on 
their phones. I suggest building up a cable from scratch. It is fairly 
easy to do, and would cost about R10.  If as much. You could source the 
components at any electronics shop... (Maybe a bit difficult in 
Saldanha, but try TV and Computer repair shops).  You could also buy 
general components from the following companies, and I'm sure they would 
be able to ship to you. (Depending on how much you are willing to pay 
for shipping I suppose). The connector part numbers for serial ports are 
usually called DB9 male and female.

down, but should go up again soon)

I hope the information help you. If not ... mabye next time.

Greetings
Henk
