Cube, a chess program from the early 80s, written in Fortran IV by Lloyd L. Lank and James A. Lank, at that time affiliated with United Computing Inc., Kansas City, Missouri. Cube ran on a Cray-1, participating as Cube 2.0 at the ACM 1980, and as Cube 2.1 the ACM 1981.

=Description= A brief description is available from the ACM 1980 tournament booklet : Cray-1, United Computing, Kansas City (512k; 64 bits; 80,000,000 inst/sec)

Cube 2.0 is an updated version of Cube 1.1. It executes on either the Cray-1 or on an Honeywell 60/80 provided by Honeywell in Minneapolis. The program is written in Fortran, uses alpha-beta algorithm and iterative deepening. On the Cray-1, the Lanks say the program examines 4,000 nodes per second. This is its first ACM tournament.
