This is probably the most unique ][ clone outside of the Russian Agat - pressing the CN mode key flips BASIC into hi-res, forces monochrome mode, and lets you type in Applesoft BASIC programs in Chinese. There's built-in LOGO in the ROMs too, but I don't know how to invoke it.

What kind of input method does it use for Chinese input? Western Apple II Chinese language cards were the origin of the CangJie input method (reasonably popular for traditional Chinese input in Hong Kong).

It uses 'Pinyin' method, maybe some others as well, such as a telegraph-like 4-digit encoding.

The CEC-I was quite popular in the mid-to-late-1980's in many elementry schools in China.

This ][ clone uses 2x 64K*4 bits DRAM chips as its main memory, one 32K*8 EPROM (27256) for build-in BASIC and LOGO intepreter, 2x 128K*8 mask ROMs for Chinese fonts, and another 32K*8(27256) for Chinese processing programs,

It has integrated 5.25inch floppy disk controller, Joystick interface, and PAL color TV encoder hardware.

The CEC-I has pretty good compatibility with the Official Apple-II(Apple DOS 3.3, many games, etc). You can even add a Z-80 card to run CP/M 80.

Yeah, it should be almost perfectly compatible with software that runs on a 64K II Plus, aside from things that called undocumented ROM entry points. As I wrote on my blog, the later version 1.21 of the boot PROM actually fixed some compatibility issues that prevented ProDOS from booting.

Thanks for the info, do you know how to get into the built-in LOGO interpreter?

Let me try to find some 1980's programmer's manuals for the CEC-I. Maybe from a library...

There's a bunch of manuals on the Internet Archive collection. I tried skimming them by holding my phone running Google Translate in OCR mode to the screen but that sucks.

Here's the stuff:

https://archive.org/details/Apple_II_Chinese_Materials_Collection

Click where it says "To browse the collection, click here" to see all the files, or just download the entire .zip and see for yourself

Got it. To enter LOGO(subset) from BASIC environment, input:
]LG
(When no DOS loaded), or
]MAXFILES1
]LOGO
(with DOS loaded)
