Do both Galeb and Grundy NewBrain involve computers?
Galeb (computer) Galeb (en. "Seagull") was an 8-bit computer developed by the PEL Varaždin company in Yugoslavia in the early 1980s. A grand total of 250 were produced by the end of the summer of 1984, before being replaced by Orao.
GNU Prolog GNU Prolog (also called gprolog) is a compiler developed by Daniel Diaz with an interactive debugging environment for Prolog available for Unix, Windows, Mac OS X and Linux. It also supports some extensions to Prolog including constraint programming over a finite domain, parsing using definite clause grammars, and an operating system interface.
