[Repairs] price of a brick, cost of all tools needed to open and repair a d6 bricked XO

[Daniel Fuhry]

Hi everyone,
I browsed through your mailing list and thought that you could be 
interested in the evaluation of components necessary for unbricking an 
D6 bricked XO.
This experiment indicates problems in getting components (parts) for an 
acceptable price outside the US.
Good and bad news, you can purchase pre-assembled cables from a US 
sourcer but without group-orders or other logistic strategies it is far 
too expensive (more than $100) to order from abroad.

I examined what it would cost to buy all the components necessary to 
unbrick an XO (using a USB interface).
condition 1. I don't own any tools. (no soldering iron, no crimp tool, 
no screw driver)
condition 2. no other equipment except another (working) XO.
exception: I magically own an USB A-B cable (I ordered that one too, 
this time from an European Online Store, but it never arrived).
Important: I want to build a professional looking device that fits the 
connectors and can be used multiple times. (unbricking other XOs)

What I need:
at least 1 Philips cross-head screw driver
a serial-USB interface that works at 3.3V.
a cable with a connector that fits J1 (connector is made up of housing 
(Molex# 51021-0400))

What I bought:
1x Mini Philips Cross Screw Driver (Green 5-Pack) - $1,72 (€1.15)
1x Arduino Serial USB Board $20,95
1x CA-3286-6FT (4-pin Micro Connector, 6FT length) $7,35

Take a look at all components: http://bookbeaming.fuhry.net/parts.jpg

Looks like the most expensive part is the Serial USB Board but lets add 
shipping.
Here comes the catch if you life inside the US your order is at least 
$60 cheaper than everywhere else. (except maybe Canada)
1x Mini Philips Cross Screw Driver (Green 5-Pack) $1,72
stealth (no extra shipping), (Hongkong Post)
1x Arduino Serial USB Board $25,15 (€16,65)
$2 Handling
$2.20 (2 oz First-Class Intl Parcel Rate), (USPS, Endicia)
1x CA-3286-6FT (4-pin Micro Connector, 6FT length) $59,12 (€38.80)
$51.77 (UPS Worldwide Expedited, Zone 4)

Adding Taxes.
1x Mini Philips Cross Screw Driver (Green 5-Pack) - $1,72 (€1.15)
(tax-exempt)
1x Arduino Serial USB Board $25,15 (€16,65)
(tax-exempt)
1x CA-3286-6FT (4-pin Micro Connector, 6FT length) ~$80 (€50.81)
~$11.83 (€7.51) European Import Tax (the product required no duties but 
the value of the transport does)
~$7.1 (€4.5) UPS Modification (fee for tax collection)

That concludes that all components end up in total of ~108$ (68.61€)

~ means value is artificial (calculated) using 1€ = $1.575300
All other conversions were charged by PayPal or VISA.

Now to actually unbrick a XO the parts still need to be put together.
On the left the side of the table are the signs on the USB serial board 
and on the right the corresponding colors of the cables.
- Yellow
+ Red
RX Black
TX Green

Disassembly of the XO. (The 4 screws on the bottom - 4 screws on the 
screen and 4 screws (under the screen) for the backplate need to be remove.)
Removing the backplate of the XO.
The cable connected to the board.

Plug it into the USB-Port of another XO.
The microphone LED is lit.

What is left to do and were help is needed.
1. I would like to flash recover an XO using the recovery connector 
CN24. Is another XO able to spi recover?
2. I need to figure out the name of the manufacturer that sells the CMOS 
CC7L5RT oscillator.

What I need:
CMOS CC7L5RT oscillator 65 Mhz (???), has anybody an idea of the 
manufacturer?
a cable with a 5-Pin connector that fits CN24 (made up of housing Molex# 
51021-0500)

left side of the clock battery.)
