I have ultra-sonography(medical) in 1952! I have other technologies, that are pretty unusually special, too. I am just concentrating on the military, tech, and diplomacy aspects. I have 9 tech slots. I have asked the production minister to keep production following demand. and to reduce demand, and to research cost reductions. This seems to work like a dream. it seems, things are pretty o. k. Also, I invaded the Portuguese in Goa, and when I did win Goa, I am keeping on sending peace treaties, and the Portuguese are on a heightened state of war alert. I gave them two medical discoveries, and they took them, but refused my overtures. It appears, a South American nation has broken diplomacy, because both the Portuguese leader, and the South American leaders are perceived 'dictators', and the South American leader just manufactured a 'coup'.
