查了一下没有英文语言可选

TI-83 Premium CE 的 OS 内核语言就是 English,不可删除;法文以及其它语言倒是可以删除的语言文件。

收了一台这个工程机,还没到手,到手后看看OS版本号,但是背后K-EVT2-401,EVT2 NOT FOR SALE字样,和楼主这个不同

Hi zhoudb, this is a very exciting find!
Any chance you can open up the case? I would love to see the PCB!
Could you also check the self-test menu for the boot code version and get a picture of the serial number on the back?
Well done finding this!

There is no serial number on the back,There is a strange wire on PCB board。I didn't take a picture of the self Test interface. I will take a picture later。After the calculator is connected to the computer, the computer has no response, there is no device in the device manager, and Ti connect CE can't find the calculator.

Wow, this is the earliest CE yet! The hardware is obviously very interesting, particularly the fact that the J1A JTAG connector is present. If you could dump the OS that would be really great but there might be some issues since it is so different, the current tools might not work.

When the calculator is connected to the computer, the computer has no response, there is no device in the device manager, and Ti connect CE can't find the calculator,So I can't dump the OS of the calculator。Do you have any idea?

黑线一点用没有,直接拆了就行,红色的飞线,到可以试试,断开是什么效果

我感觉黑色的线是用来接某些外接传感器或者什么其他设备,测试的时候临时引出的线,现在并没有什么卵用了

I would not start removing or modifying things for now.
Are you sure it was plugged in all the way? I know this was an issue with early CEs, the USB port was very tight so you have to push quite hard. If not, then it seems like the USB port doesn't work. When you plugged it in, did the LED light up and did it start to charge or did the calculator also have no response? It certainly seems like there were some modifications that would affect the USB port itself...
Would you be willing to sell or loan the calculator so that one of the CE guys (perhaps critor) can test things out? If the USB port really doesn't work then we could dump it either by using a SOIC 48TSOP NAND clip on the flash chip or by figuring out which type of JTAG it is and attempting to dump it through that port. (The JTAG connector is not the same as what TI used on other models like the nspire).

I confirm that the USB cable is plugged in. After the USB cable is plugged in, the power indicator is on, and it can be charged. There should be no problem with the USB port. The same USB cable is used for my TI-84 plus CE, and the computer can recognize it correctly. There are no CE enthusiasts around me, so I can't sell it or lend it to others.

What mrwompwomp was trying to say, is that the first production CE in 2015 had a hardware issue. The mini-USB port had an abnormal resistance to the cable insertion. So you could think the cable was fully inserted when it wasn't.
2013-2014 prototypes may have the same issue. Your recent TI-84+CE doesn't have such issue.


Also, I think he was asking if you would accept to sell it to him. ;-)

昨天又上架了一台,我拍了。

刚刚收到,计算器大部分都和上面回复的情况是相同的,包括系统、BOOT之类的。

那啥,部分图片方向不对,大家转转脑袋哈233,此外文件太大用了图床,不知道你们能不能看到图片。






后面的序列号不一样哈哈,我的是211。

我的这台连接电脑是有反应的,不过不能传文件,会报错。

截图倒是没有问题。

本来想用CEmu转储ROM但DUMP的程序传不进去。



计算器信息如下。



7月26号15:00更新:

尝试使用Ti-connect CE 5.0以及Ti-connect 4.0/1.6.1均不能导入文件。

其中Ti-connect CE报错相同。
Ti-connect报错如下:

此外Ti-connect对于该计算器识别有误:

连不上电脑也许是那两根红线?其中一根把USB的Data+和Data-短路了,电脑应该检测不到设备
