BASIC Computer Games – Anno 1978 – Versione originale: DEC RSTS-11 – Adattamento: Commodore 64 Basic V2
Continua il nostro viaggio alla scoperta di listati che hanno fatto la storia dell’informatica. Questo Super Star Trek é decisamente uno di questi, tant’é che la versione originale di Mike Mayfield del 1978 é stato ripresa ed adattata per diverse piattaforme nel corso degli anni.
La versione presentata in questo articolo é un adattamento del codice presentato sul libro “BASIC Computer Game” al Basic V2 del C64 ed alle sue 40 colonne.

Note: Questa versione é stata adattata al Basic V2 del Commodore 64 e alle 40 colonne. Altre modifiche sono state apportate nei colori, nella visualizzazione del testo e nella correzion di alcuni bug. Nonostante la riduzione dell’area di gioco, abbiamo fatto in modo di preservare tutte le informazioni mostrate dalle schermate originali.
Scopo del gioco
Sei il capitano dell’astronave spaziale ‘Enterprise’ con la missione di trovare e distruggere tutte le astronavi Klingon nella galassia che stanno minacciando la Federazione Unita dei Pianeti (United Federation of Planets).
Hai un numero di giorni (stardates) predefinito per completare la missione e distruggere tutte le astronavi Klingon. Entrambi questi valori sono generati casualmente dal programmma e variano di partita in partita. La galassia é divisa in 8×8 quadranti, a sua volta divisi in 8×8 settori.
Il gioco é piuttosto complesso ed é necessario leggere il manuale per padroneggiarlo.
Manuale: Istruzioni in Inglese – In attesa che venga messo online il file con le istruzioni, anche questo un programma in Basic da adattare alle 40 colonne, andate a pagina 157 del manuale che vi ho linkato. Nonostante le istruzioni, vi renderete conto che il programma é decisamente ostico e sconfiggere tutte le astronavi Klingon nei giorni a disposizione non sará una passeggiata.
Qui di seguito trovate il codice da copiare sul vostro Commodore 64.
Il codice é pronto per essere copiato su CBM prg Studio.
Attenzione – Ci siamo resi conto che nel listato i caratteri ‘>’ e ‘<‘ potrebbero venir sostituiti dai rispettivi encoding html ‘>’ e ‘<’. Nel caso, sostituite questi valori direttamente su CBM prg Studio.
