NOTE: EightyOne emulates a wide range of Sinclair computers, so it must be configured to emulate a ZX-81, preferably with the 16K RAM expansion, since Kaitei Attack may run out of memory mid-game.
\n– Options -> Hardware -> ZX81 (on the Sinclair tab), select “16k” under “RAM Pack”.<\/p>\n

Load the dowinski.tzx tape file, type J, Shift-P, Shift-P (the resulting output should be ‘LOAD “”‘), press Enter then play the tape;
\nNOTE: EightyOne does these steps automatically upon loading the tape image.<\/p>\n

After the program finishes loading, press R (for ‘RUN’) then press Enter to start the game.<\/p>\n

Undersea Attack<\/p>\n

How to Play
\nAfter doing RUN, A black warship will appear at the water’s surface. The score appears at the upper right. At the start you have 100 score. A torpedo will appear from the lower left and go from left to right.
\nAim for the warship’s control room, and when it lines up directly below you, press the [NEWLINE] key. Upon doing so, the torpedo will start ascending from its current position. A clean hit at the control room will up your points by 50, whereas missing it even slightly will down your points by 20.<\/p>\n

Program Explanation
\n1 -30 Warship and score PRINT
\n40 -80 Torpedo left-right movement and input handling
\n90 -120 Torpedo ascending movement
\n130 Collision handling
\n140 -150 Miss processing
\n160 -170 Hit processing
\n180 -200 Round processing<\/p>\n

Variable Table
\nS……Score
\nA……Horizontal pixel coordinate
\nB……Vertical pixel coordinate<\/p>\n

THE 0-FIGHTER<\/p>\n

STORY
\nIn World War II, Japan’s military had manufactured the invulnerable Zero figther. One day, the enemy forces staged a surprise attack. It is not known from where the enemy comes from. Skilfully piloting the 0-Figther, you shout “Now!” as you start firing your guns.<\/p>\n

How to Play
\nAfter doing RUN, the Zero-Figther will start flickering. Afterwards, the position where the enemy’s missile is is drawn. Using the keys, fire your missiles to hit the tip of the missiles.<\/p>\n

KEY Controls
\n[5] goes left, [6] goes down, [7] goes up, [8] goes down. Pressing [A] fires your gun.<\/p>\n

Program Outline
\n1 -4 Enemy and Zero-Fighter starting positions
\n11 -50 Zero-Fighter movement
\n70 -76 Enemy movement
\n101 -106 Zero-Fighter position to bullet position exchange
\n112 Collision detection
\n113 -140 Enemy movement
\n150 -165 Bullet flight processing<\/p>\n

CHECKER FLAG:
\nEditor: We keep getting great Sinclair programs. Even though there’s only 2 here. However, these were easy to understand and therefore the most suitable for BeMaga.
\nDr. D: Agreed. The article has entries on the program’s outline and varables, so I don’t have anything to say.
\nEditor: These programs are simple, so those typing them in should think of ways to make their own variations of them.<\/p>\n

\u2605Short programs are great! Long programs are a pain to input. (Asahikawa, Hokkaid\u014d\u30fbKazuo Kurosawa, 32 y.o.)\u2026\u2026\u3010Editor: I can’t understand long programs. I much prefer the short ones…\u3011
\n\u2605I’m very pleased with the Operation Port project. Please do the monitors and routines of the better models! (Tokushima\u30fbManabu Kashiwagi, 32 y.o.)\u2026\u2026\u3010Editor: Certainly. Dr. D: Please wait a while more.\u3011<\/p>\n","protected":false},"excerpt":{"rendered":"
