that's the #1 issue - getting the chips. Soldering them could actually be done at my university - there're many hardware labs working on all kind of things.

and how many chips does $200 get you?

WARNING!! slightly off-topic

Doesn anyone have or know the 6000 expansion connector pinouts? I'd really like to make use of it...

Like I said on the other thread where you posted the same question, I do have a spare Samsung 128MB nand flash chip.

er.... were you talking to me albert.r ? My question wasn't about the chips, hence the offtopic warning.

i just searched google for the chip number. there are a couple of retailers u have to ask them for quote. its like entry how many and the price willing to pay but u cant get less than $200

albertr, sorry I dind't notice that. I'm interested. Do you have the chip reference? (I may need to get a special model for the bootloader to find it) How much would you sell it?

any news on this?

I had a 128MB flash disk with a chip that would have worked, unfortunatly it went missing

couple of things to note, the 2GB flash chips from sharp are pin compatible, i am thinking of buying an ipod nano to rip apart.

i have a c3k that i am willing to use to test the hack, however it would be better to keep the 16MB chip in and use it to bootload the c3k and use the kernel mtd drivers to detect and itilise the chip, this means the max using flash chips is 2GB + 16MB instead of 4GB unless you want to hack the rom, lukily i have no problems with doing that ethier

i dont see why larger chips wouldnt work for any other zaurus unless there is somthing i havent read about on this fourm.

so put me down for the ram chips and flash, if the flash works i will upgrade it to 4GB later. if you do get the RAM chips could you make sure we get the highest speed ones avalible, i want to see how fast i can make my ram bus go

I saw that someone actually attempted replacing the flash on a 6000L here.
Anyone know how to contact this guy ? (no email on the site)

I have a C760 on which I can try on ...
I have a few questions then:
I have a 256 lexar CF card with a K9K2GO8UOM chip can this be used ?
the CF card has a few problems (I cannot write to it any more) .... is this dew to dammage on the nand2CF pridge inside or is it the nand that's broken ?
pdaXrom now uses u-boot .... will this work around the sharp boot loader problem only working with limited chips ?
If this is true can any other compatible chip be used ... I have two 1Gb CF I rarely use now that I could open up ... what other chips would be compatibe ?

That was Speculatrix and he bricked his first 6000L doing it. He made a FrakenZaurus out it by combining it with a 6000L that fell off a roof.

I would strongly suggest that if you're going to risk damaging your Z, you really want to use the newest chip possible! However, it's useful to know where this device has been used, so far it's been a bit elusive.

I really don't know enough about the way the Z boots; however, I believe that Guylhem has analysed the device tables in the Z's boot code so he was able to identify compatible devices.

"frankenzaurus" - ROFL!

Breast pocket not good place for a 6000 when bent down to pick something up on the roof...Rather than dive after it and go off the roof, I opted to sadly watch it slide away. Display was hosed, but seemed otherwise 'thumbs up', was close to 2 meters give or take, on to concrete I was too impressed to be all that upset.

Lesson learned, I have a secured solution for my next Zaurus when I'm carrying it.

I would love to mod one in to my car.

Hey, how's it going? The thing I never understood was: what were you doing on the roof with a zaurus in your pocket? Running kismet and snooping your neighbour's porn download?

FYI, I was just looking at a C3000 p2rom:

The table of supported NAND chips starts at offset 0x1c4a0.

Supported are:
Toshiba TC58512FT (Maker 0x98, Device 0x76, 64MByte)
Toshiba TC58DVG02AFT (Maker 0x98, Device 0x79, 128MByte)
Samsung K9F1208U0M (Maker 0xec, Device 0x76, 64MByte)
Samsung K9K1G08U0M (Maker 0xec, Device 0x79, 128MByte)
Samsung K9F2808U0C (Maker 0xec, Device 0x73, 16MByte)
Samsung K9F5608U0C (Maker 0xec, Device 0x75, 32MByte)

Erase size 0x4000, block size 0x200, oob size 0x10 for all of them.
Another value (bank size?) is 0x4000000 for all of them except the Maker 0xec Device 0x76, where it is 0x8000000.

In theory any chip that has the right Maker/Device and matching parameters and is command set compatible should work.
I'd try looking at 128MB or 256MB usb sticks or 256MB/512MB CF cards for matching parts (My old 64MB usb stick uses a TC58512FT compatible TC58DVM92A1FT 64MByte TSOP48, but the sticks PCB has room for two chips).
