Quote by [[Aaron L. Futer]] about the ICL 4-70 computer at the Institute of Control Sciences:
<blockquote>The algorithm is implemented on a computer with the IBM-360 command system. The unit of information of this computer is a byte — 8 binary digits (bits). The command system provides for work with the following values: byte, halfword (2 bytes), word (4 bytes), double word (8 bytes), variable length field (up to 256 bytes). Performance depends on the command format, but on average it is 300 thousand operations per second. The machine's operative memory, available to the programmer, is 330 thousand bytes. Capacity of external devices: magnetic tape — 20×10<sup>6</sup> bytes, disk — 7.2×10<sup>6</sup> bytes. The operating system allows several programs to run in parallel.
To encode the chessboard, we use 64 bits — a double word. Bits are numbered from 0 to 63 <ref>Translated by Google Translate [[Edward Komissarchik]], [[Aaron L. Futer]] ('''1974''').
