Lithia's Core / t'

IN-2014 is the display module for the Bendix CN-2013 VHF COM/NAV, which in turn belongs to the BX2000 Family. This display shows glide slope deviation and other navigational information using a gas discharge display.

It, unfortunately, means it needs high voltages to operate (to be specific, ±115V DC), so I can’t really test it with the equipment I have at hand.

On the internet, there isn’t much information about this display module, so I purchased an installation manual of the CN-2013 system, and the following is some important stuff specifically about that display module. I hope this is helpful for somebody.

感谢Zephray大佬的推荐，这次用的是Lektor框架。Lektor是一个极简的静态网页框架，基本可以看作是带一点宏的Html编辑器。过去这些年里我一直用Wordpress，但到今天为止我都没有喜欢过它。毕竟Wordpress编辑表格的功能还不如直接写html强，这次新网站就直接用html了，还可以美其名曰“IE4.0兼容”

就像名字所说，模拟巫女.com，这个网站主要的内容都和模拟信号相关（包括模拟电路和RF），未来Lithcore.cn就只发数字电路和计算机相关的东西了。

不过话说回来，到目前为止没什么人会来看这个网站，所以暂且当作“不为人知的2004年互联网神秘地带”发展吧！

I always held the highest respect to the forerunners of electronics in the 80s and earlier: they managed to produce a myriad of circuitry crafts with extremely limited access to documentation and other resources. It was an era when the community culture is highly cherished and established mainly through magazines and books. IEEE, being one of the leaders of science & engineering communities, had been releasing bounded volumes about specific topics for quite a few decades. These bounded volumes are known as the “IEEE Press Selected Reprint Series”.

The objective of this post is to make an unofficial catalog of those books. The content will also be listed for easy indexing.

Note that, despite all the historic and aesthetic value about them, these releases have been totally obsolete for too long. If you’re a student like me, do not waste your time reading them – go for something newer instead.

If possible, I really want to make this into a wiki for easier indexing. IEEE must have published a huge amount of these books, but there is not much information on the internet.

This page is still under construction…

Flashing 10C, 11C, 16C ROM

16C is still extremely buggy, the decimal mode is almost unusable, probably something to do with ALU mode switching; 15C doesn’t work at all because the 12C+ firmware doesn’t support paging. 10C and 11C should work with no problem.

Notice: The following sequence only works for REV2 (with rev.2 written on the back plate). It will not work on a more commonly seen REV 1, which I don’t possess yet. It should work in a similar way, but I don’t think REV 1 allows flash access without forced erasing, which deletes the nut emulator.

How to (12C+ rev2):

1. Extract RAW Nut Processor ROM binary file from 10C or 11C.
2. The original ROM file is 12-bit per word, convert it to 16-bit big-endian binary. (You should look for certain ARCHIVEs of the nonpareil emulator for the ROM file)
3. Flash the binary file into address 4800-77FF
4. Enjoy
