Silas Warner’s Castle Wolfenstein, published in 1981 by Muse Software was a wildly popular game and spawned a successful direct sequel, Beyond Castle Wolfenstein, as well as a number of “spiritual successors” and homages.
There were (at least) two versions of the manual. This is the earlier one, featuring a purple cover. The later version (seen on Asimov, the Internet Archive and elsewhere) has a brow(ish) cover. Other changes include:
- The font has been updated from the typewriter script to a more professional look, and the text has a new layout to match.
- All instances of the word “Muse” now appear in caps.
- The “Castle Wolfenstein” banner above Warner’s name on page 1 has been updated.
- A copyright notice has been added to page 2.
- On page 3, the paragraph about the use of Super-Text has been slightly reworded and the copyright notice no longer appears.
- The drawing of the running soldier on page 4 has been replaced with the one that appears on the cover.
- The ad on page 10 featuring other software from Muse has been updated with more recent titles, and no longer references their cassette offerings, or Integer BASIC/Applesoft ROM requirements for certain games. An Apple trademark notice has also been added here.
