屏幕的布局也不一样,这是34根排线的屏幕布局,很杂乱 DSCN0900.JPG
这个是38根排线的屏幕布局,明显整齐了很多

Very interesting. :)

Do you also have the calculator datestamps for each board ?
It's the 6-7 characters code present on the back at the right of the serial number.

Something like X-0000 or X-0000X

Pictures of the back of the main boards would be nice too. ;)

X is for a letter, and 0 for a digit.

For example, the datestamp below is P-0413J, as you can read on the right of the serial number :

The first letter is the manufactoring site.
P = Inventec (Pudong) Corporation

The last letter if present is the hardware revision.
No letter means it's the 1st released version.
A = 1st hardware revision = 2nd hardware version
B = 2nd hardware revision = 3rd hardware version
... and so on.

Do you have pictures of the other side of the main boards ?
It's usually interesting because that side does have the board reference and the memory chips (SDRAM, NAND and on some revisions NOR).

楼主你好,想请问一下NSPIRE自己换屏幕麻烦么?需要用到什么材料,还有屏幕在哪里买呢?谢谢

不麻烦啊,看你怎么换了,是换屏幕总成,还是只换液晶啊,屏幕总成的话就是排线40根和38根的区别,如果只换液晶的话,需要3处排线,两处是26根的排线,一处是30根的排线,另外就是液晶屏幕后面的散热铝板双面胶很黏,没有热风枪什么的不好去下来

屏幕总成换起来是相当容易了,即使没有排线的话,手工飞线也用不了一个小时就能搞定,只换液晶就麻烦了,先要把旧的分离,很费事,三处排线,操作不当很容易排线弄断的
