Intel vs. NEC: The Case of the V20's Microcode

I've got an old V20-based NEC laptop (the PC-1702, arguably an Ultrabook in its day) and I really should dig it out and try the 8080 emulation out. It doesn't look like it'd be too difficult to execute short 8080 routines. (Getting CP/M up and going looks like more work than would be reasonable for fun.)

Intel 80186 had been launched in 1982, simultaneously with 80286, i.e. 2 years before NEC V20/V30, so NEC had ample time to update their instruction set.
NEC V20/V30 also implemented a mode when it directly executed Intel 8080 instructions, presumably to be able to execute some old CP/M applications.
I also mis-remembered the CPU. It's a V30, apparently.
I carried mine in high school for note taking. It was a very nice little machine, albeit quirky. With no built-in mass storage aside from the "silicon disk" (2MB SRAM-based battery-backed SSD) using it was an exercise in using lightweight software.

It's shown on the Spring '91 catalog cover!
22NICE is still available and will almost certainly run on a PC-17-02 using the hardware 'emulation'
Not sure how much truth there could be in this or if it's just a good sounding tech legend based on this lawsuit but if anyone has any details on this story that would be great.
The legal action over the V20 started when NEC sued Intel, not the other way around. I wonder if Intel held off suing NEC first as they felt that their legal case was weak - the two microcode programs were very different after all. Only during discovery would it have become clear that members of the NEC team who had seen the 8088 code had also worked on the V20.
In the end a four year court case was probably a good outcome for Intel and starting the case possibly a mistake by NEC.
We sometimes forget/ignore the fact the Soviets had very, very good engineers even if the system they were embedded in limited their achievement.

That is... an accurate description of this string, yes. That is to say, it translates each English word with what could be a good translation in some context (except for one misspelling). The resulting sentence, though, is completely incoherent and impossible to understand if you can’t back-translate to English.
(The alleged translation here was obviously done by some who didn’t know the language. As a side note, however, it’s also a fairly hard phrase to translate: slogans often are, because you don’t have as much surrounding text to reshape around any syntactical awkwardness; but this one specifically as well, because Russian lacks a good counterpart of the phrase “care enough to”, unless you can round it off to “need to”.
And what do you know, I just checked both Google Translate and DeepL, and they both produce passable Russian meaning the wrong thing. ChatGPT 3.5 produces a plausible if imprecise try, then a marginally ungrammatical one once asked for more precision, and gives its usual slippery vacillations when asked if the translation is precise.)

So I doubt this part, unless the authors only had an English translation of the Russian original at them.
Clearly, this will be a complete surprise to you, but in 1987 we didn't have google translate and chatgpt to think for us.
But I didn’t actually mean to criticise, really. It’s just funny. (Not nearly as hilarious, say, the Russian passport in The Bourne Identity, but still pretty funny.)

Oh...you have some weird axe to grind. Figures.
