On my MD-430 (aka GD-73), which has the C7000 chip, it is detected as "walkie-talkie-C7000" in the Device Manager, after a (not so easy / smooth) driver installation process.
So I assume other C7000 based radios might be seen as this as well, if they use the same driver.
This new 1801 A6 is certainly interesting. Given the confusing world of Baofeng analog radios in the past, I am not too surprised about this. Ironically the confusion on the analog world is about different shells, specs, minor features, packaging etc, but the chipset stays the same.
The MD-760 is still available, but mostly sold out of China. I haven't seen any reseller outside of China carrying this model. I think one can buy one from Aliexpress as I have seen it listed there not too long ago.
