I have noticed in Bitsavers.Org that Zilog provided datanotes for Z8 architecture microcontroller that I have too. What if I make small communications key through microphone plug at an aircraft so I can become till a ATPL-pilot. I planned to buy last production Tupolev Tu-104 three pieces cheap might partially prebuild to using with freight computer items Norsk Data and Tandberg Data, and much more options later, only domestic in Norway. Also, I could using original 4 pieces of Il-62 from Interflug or Domededovo or CSA to freight fishes till and from China. In conclusion with Russian planes website, many runs only 1-4 years such as SibaviaTrans and Tesis which I mentioned in this post already.
