Title: Difference betwen c760 and c860.
Post by: Joshp on March 30, 2004, 10:58:51 am
What difference if any is there betwen the c760 and the c860.  Form what I read there both the same hardware, so does that mean I can use Open Zaurus for the c760 on the c860?

There is no practical difference between a C860 and a C760 besides the paint job

Can I use the 860 rom backup on a 760 without problem?

amrein,

If you are talking about the NAND backup (SYSTC860.DBK) then yes, you have to rename it to SYSTC760.DBK for the C760 to recognise it.
After the NAND flash, your service menus will be red - don\'t know of they are normally red on the C860 or not. Also then you will need to use the C860 updater.sh as your machine will be identified as a C860.

If you are talking about the backup done with backup/restore app then yes again, just rename the file again.

If you are talking about other roms, then most probably will aslo work.

Am I understanding this correctly?  If the hardware is the same \"except for the paint job\", can I simply purchase the somewhat cheaper 760 and use the updates ROMS and actually have an 860?  :!:  :?:

You see, by reflashing you can\'t get better video chip that 860 has, but you can use your 760 as a flash drive (or maybe card reader) just like 860. Just reflash to pdaX ROM and you\'ll get it plus many additional features.

I didn\'t realize that the 860 has a better video chip than the 760... can anyone confirm this with technical specs of both?

They both have the ATI W100 (as does the C750 I think).
Otherwise you couldn\'t use the kernel for the C860 on the C760 (and you can).

If you have supporting documentation showing that the C760 and C860 have different graphic chips, I\'d love to see it cause everything I\'ve been able to find in English or Japanese says they both have the W100.

Sorry you are wrong, the C760 and C860 have identical NAND chips - exactly the same size and model.

All C models have ATI W100 chips, even C700.

Sorry, that was the type of display. Display of C760 is TFT CG-Silicon and display of 860 is transreflective one (you can use it outdoors, when the sun is up)... Someone misinformed me about video chips...

Are you sure about the displays?

Display is supposed to be the same too. Only the newly released 6000\'s have the tranflective screen (which can be read outdoors).

I think that stat is wrong too.

So can the displays of the C760 and C860 be seen in the daylight or not?

I\'m ready to trade my SL-5600, but daylight visibility is a must...

If you turn brightness up to maximum it is viewable. It\'s a pretty dim image, but if you needed to look something up you could. If the primary place you\'d look things up is outdoors, I\'d avoid a 760

Well Stu, there are alot of documents stating that the c860 has 128 megs of ram and 64 megs of rom. If there were no difference what would be the advantage of buying the other. It\'s not like getting a car were the only upgrade is different paint or a cup holder.

Maybe it\'s like getting a model 2004 car instead of a model 2003.

As I understand it, the 860 is nothing more than the *next* model-
that is to say, the replacement for the 760, which is no longer being produced or sold by Sharp.

In fact, C760 (and C860) users in these forums have reported that their
devices have 64mb of SDRAM, and 128mb of flash NVRAM (aka ROM).

Sharp has no incentive to differentiate the two models; the C860 is selling, new (in Japan) for the same price that the C760 sold, when it was released.  Merchants who still carry the C760 are selling it at a discount, just because its \"old\", but the only different features are onboard software, and case color.

Whatever the documents state, I\'d be more inclined to trust savvy users who have poked at the internals of their own devices.

Without a doubt the C750 keyboard is easier. You can actually type a lot more on it faster, though after quite sometime holding it in your palm and thumbboarding it, it palm aches a bit. Then I usually lay it down on my lap (or table) and finger type (slender fingers).

Actually the 5000D keyboard was good too, but only for short messages and all that. For really long message typing the C7xxx keyboard is definitely a plus.

I have tried reading my C750 screen in daylight and you will have to kind of peer at it at angles to really make out whats written in small print.
As treke said - if you want to use it in daylight a lot, avoid the C7xx series (or else you will have to look for shaded areas all the time).

From the Sharp Japan site http://www.sharp.co.jp/corporate/news/slc760.html (http://www.sharp.co.jp/corporate/news/slc760.html) and http://www.sharp.co.jp/corporate/news/slc860.html (http://www.sharp.co.jp/corporate/news/slc860.html)

C760

Flash 128MB(ユーザーエリア約65MB)
SDRAM 64MB(ワークエリア)

C860

Flashメモリー 128MB(ユーザーエリア約65MB)
※ユーザーエリアは翻訳辞書データなどの削除可能なプリインストールデータを削除した場合の値です。
SDRAM 64MB(ワークエリア)

The extra bit in the C860 entry says \"the user area value is the value after deleting the preinstalled translation dictionary data.

Looking at all the other data I have in Japanese gives exactly the same specs - and Japanese electronic advertising is very big on specs.

From what I have read on Japanese sites, the change from C760 to C860 was to focus more on the Business market. Hence the highlighting of the added Eng-Jap translation software and the cheap wifi/dial-up/phs isp costs available only to C860 owners.

The only advantage is the new software packages and the fact that except for leftover stock you are unable to purchase the C760 now in Japan, however the C700 and C750 are still available to buy and advertised by Sharp in the electronic stores.

coolass - check your sources....

the 860 is exactly the same as the 760 with regards to hardware... the ONLY difference is the paint job.

they both have 128mb Flash and 64mb SDRAM, none of the C series Zs have the transreflective displays.

the only differece between the the 860/760 and the 750 is that the 750 has 64/64.

the 700 is a different story

Sorry I didn\'t know a mistake would be so costly. But their are sites that say the same, guess I\'ll stick to what I know and that\'s my sl-5500 & sl-6000.

The C860 has a CG Silicon display (described as TFT semi-transmissive by Sharp). It\'s identical to the C760\'s, and the look the same side-by-side. I can see the C860 screen outdoors, but I wouldn\'t want to spend a lot of time working outdoors. Though I don\'t find transflective PPC screens much better.
