Исправление vodz, (текущая версия) :
Как вы достали выкручиваться и приводить фигурные цитаты. Факт в том, что именно до pdp-11 нормального Юникса, а не прототипа не было, в 69-ом написали прототип на ассемблере, а в 70-ом, который и является годом рождения Unix купили pdp-11 и сделали в 71-ом C и нормальный Юникс.
However, the PDP-7 was already obsolete when it was used for creating the first version of UNIX, and thus in 1970 the UNIX group proposed purchasing a PDP-11 for $65,000. The PDP-11, which had just been launched that year, incorporated some important advances (including greater ease of programming), and it became a highly successful and influential model. It was DEC's first and only 16-bit system.
In 1971, the group used their new PDP-11 to rewrite UNIX in a high-level language, instead of its original assembly language, so that it could more easily be ported to (i.e., transferred to) other types of computers. They briefly tried using Fortran before creating their own language based on BCPL (Basic Combined Programming Language), which they called B. They then extended B to produce the C language, which is still in widespread use today, after which they rewrote the UNIX source code in C. This made it easier to port UNIX to run on new hardware, as all that was needed was a C compiler to convert its C source code into the machine code for the specific type of computer.
ладно бы Э85 с убогой ДВК-3 сравнили...
Вот именно, ДВК была убога, некий персональный переросток младших pdp. А Э95 с 32-битными СМ1700 конечно не тягалась, но зато с остальными чуть младшими моделями всех уделывала. Но вот подключать графику и цвет на CM1700 мне доводилось. Та ещё песня.
