А ты четай по буквам с самого начала, а не по диагонали
Автор оригинала: Ken Shirriff Недавно к нам в руки [в Музей компьютерной истории в Маунтин-Вью, Калифорния] попали часы, летавшие в космос с миссией «Союз» («Бортовые Часы Космические», или БЧК).
"Electronic digital clocks (referred to as БЧК BChK) are intended for: • issuing time information about the current time with a resolution of 1 second; • crew alert about the occurrence of a given point in time; • timing of individual operations; On the front panel are located: - toggle switch “ВКЛ VKL” - turning on the power of the watch, - “Работа-коррекция Work-correction” toggle-switch - switching on the working mode of operation or the correction mode of the clock, - “ЧТВ-ОП ChTV-OP” toggle switch - connection to the upper digital indicators current time clock (ЧТВ ChTV) or siren (ОП OP); - button “ПУСК. ОСТАНОВ. СБРОС - START. STOP. RESET ”- manual control stopwatch - digital indicators “ЧАС. МИН. СЕК - HOUR. MIN SEC ”- indication of the current time or time the alert was set, - digital indicators “МИН. СЕК MIN. SEC ”- time indication second measure, - The “ВВОД ENTER” button is used to enter temporary notification information. The clock is turned on by moving the toggle switch “ВКЛ ON” to the upper position when the remote control power is on. The БЧК BChK have an internal autonomous generator and an input for external highly stable pulses. The stopwatch can work in two modes: manual and automatic. Automatic control of the stopwatch is used to chronometrify the operating time of the propulsion system and has priority over manual. Upon the formation of the “Включение СКД SKD Enable” command, a stop, reset and start of the stopwatch occurs. By the formation of the command “Отключение СКД SKD Shutdown”, in the presence of the sign “Маневр Maneuver”, the stopwatch"
Вот о том я тебе и толкую. Для нас закрытые передовые технологии, и никакой расслабухи на ширпотреб.
А теперь они там смакуют:
The surface-mount integrated circuits, on the other hand, were soldered to pads on top of the board. This is more advanced than 1984-era American consumer electronics, which typically used larger through-hole integrated circuits and didn't move to surface-mount ICs until the late 1980s. (American aerospace computers, in contrast, had used surface-mount ICs since the 1960s.)
Why does the Soyuz clock contain over 100 chips instead of being implemented with a single clock chip? Soviet integrated circuit technology was about 8 years behind American technology and TTL chips were a reasonable choice at the time, even in the US. Since each TTL chip doesn't do very much, it takes boards full of chips to implement even something simple like a clock.
