I have quite a few "ebooks" with "old" games.... David Ahl programs were among my fist programs.... I still have an actual hard copy of his 1978 book....
Line numbers and text. The many, many, many hours of keying in those listings.... All those years ago... and I 'still' can't type... lol There is something said for those old games. The ability to stir the imagination. Simplicity of plain text and fitting them into limited memory. 4, 16, 32 and 64k of ram.
I only hope that, during the "conversion", that the "feel" of the games are not lost.
"I hope someone else enjoys / finds this useful."... You're "preaching to the choir."
