*In West Germany, some distributors released it with overclocked CPUs,
advertised as 3.2, 3.6, or 4MHz. Unmodified EAS PCB photos show only a 3MHz XTAL.
Though model EAS-C(Glasgow) had a 4MHz XTAL
A condensator/battery keeps RAM contents alive for a while when powered off.
Note that EAS doesn't have a "new game" button, it is done through game options:
