I found it as part of the ZCN repository:
https://github.com/jamesots/zcn

The C source has been modified for VT100 compatibility and some minor
changes have been made by me (Anna Christina Naß acn@acn.wtf.

bs.com is the compiled binary.

See the *.txt files for more information.


Modes

-   -b selects a "blitz" variant
-   -s selects a "salvo" variant
-   -c permits ships to be placed adjacently

The "blitz" variant allows a side to shoot for as long as it continues
to score hits.

The "salvo" game allows a player one shot per turn for each of his/her
ships still afloat. This puts a premium scoring hits early and knocking
out some ships and also makes much harder the situation where you face a
superior force with only your PT-boat.


Keys

To position your ships: move the cursor to a spot, then type the first
letter of a ship (using CAPITAL letters) type to select it, then type a
direction ([hjkl] or [4862]), indicating how the ship should be pointed.
You may also type a ship letter followed by
r' to position it randomly, or typeR' to place all remaining ships
randomly.

Compiling

HiTech C has been used to compile it, but it needs a lot of free memory
(TPA).

For compiling, I used the command c bs.c in CP/M.
