No. KNG can only run on either Windows CE or old Windows systems. I don't know if it is possible to emulate KeySoft, maybe with an older version that doesn't require a key file. I may try to rip the system files out of my VN Classic, which is running KeySoft 5.1

So when you hear Echo speech, all but the last step, that of actually generating the sound you hear, was done in software running on the Apple.
>> If the Textalker source code still exists anywhere, I don't know it, and wouldn't know who to ask. Even if it did, it would almost certainly be written in 6502 assembly, the 6502 and its variants being the microprocessor used by Apple II computers. There was a version of the Echo for PC, but again, the Textalker software would probably have been written in 8086 assembly.
>> The bottom line is that emulating the hardware would probably not be a problem, but that wouldn't get you much. Textalker would probably have to be completely rewritten from scratch in order for it to work on anything modern.
>> A possibly more attractive idea would be to have a really stripped down Apple emulator which did emulate the Echo card, and create a custom disk for it which could interface with NVDA running on the PC in order to have the Echo act as a speech synthesizer plugin for NVDA.

>>> Yes, MESS itself is completely open-source. The problem is that the Echo II card is being directly emulated. So if you wanted to use it in external applications you would have to find a way to get that emulation working for all the parts of the card (the TMS5220, the text-to-speech part, the audio output) and I'm not sure how that would work.
