I have taken the original 1970s source code of the 80 column printer terminal based simulation and converted it to run on a 22 column Commodore VIC-20 (32-35k) ...No mainframe required!
Whilst undertaking this conversion I have added numerous subtle enhancements, including "helpers" for navigation & photon torpedo targeting and long range scanner interpretation guide. I've re-engineered and refined many stats, charts & data outputs. I've also added some user-friendly features and extra summary data readouts. All whilst keeping to the exact gameplay experience of the original.
This program is 100% text based and uses ZERO cursor control codes, only carriage returns, just like the mainframe terminal-based games of the 70s.
Converting an 80 column program to run on 22 column computer was VERY difficult. There may be bugs and/or formatting issues. Please let me know.
