We all know that the MSX standard was designed as a home computer mainly. Yes, there were few exceptions for specific tasks like those MSX models with dedicated A/V or music capabilities like Philips NMS8280, Sony HB-G900, Sony HB-F900 or Yamaha CX5M/CX5M II, CX7M, etc which were probably used in TV and music studios. On the other hand and If I'm not wrong we also had the MSX at Russian schools, right? I don't forget the MSX in the MIR space station but this was something really uncommon. :P
I decided to open this thread after read this post from the JaviLM user site. He explain how the Spanish government implemented in the 80s a test to get the driver's license where some MSX computers like Sony HB-F9S, Mitsubishi ML-G1 or Philips NMS8245 were used to check your reflexes and coordination (read the post for detailed information). It seems that today the same method is used with modern machines but, as it's pointed out in that post, the best part of this is that the test it's still working in some places with real MSX machines!, I precisely did the test few months ago and I can assure you this LOL!
I also remember that some years ago (not many years) I saw a Philips NMS8235 plus green monochrome monitor in a office of the Spanish Ministry of Finance. So the question is simple, do you remember seeing an MSX in a professional environment? ;)
