A downloadable game

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.

I now have a real VIC-20 machine. It is very tired (electronically speaking) and the video output is rough. It's apparently very common on VICs. So, I will be adding a totally monochrome version of the game in the disk image file. I've already tested it and it's MUCH much clearer this way. Uploading very soon.

Done.

Well, this is just awesome.  In theory, do you think the program would fit on a 5 1/4" and play on a 32k expanded Vic?

Thank you! Yes, indeed you could.

Most screenshots are from previous version. There are slight improvements with latest update (v2.7).
