The ECS was the only "computer" I had until my last year of High School.
One of the first web pages I created in 1997 contained a collection of
my ECS BASIC programs.  The "Christmas 2018" version of jzIntv added
support for Aquarius peripherals, so now it was possible to recreate my
best ECS BASIC games and distribute them via Aquarius tape images.  Here
are the instructions to play them.
__________

[Number Cruncher I]

 1. Launch jzIntv with Checkers and enable ECS.
 2. Select BASIC at the ECS menu.
 3. At the BASIC interpreter, type "CLOD NC1A" and press Return.
    (That's Number Cruncher 1, program A)
 4. "SET" will appear.  Press any direction on the disc.
 5. "GO" will appear, replacing "SET".  Press any direction on the disc
    again.
 6. "LOAD" will appear, replacing "GO".  Wait until the cursor
    reappears.  "NC1A" will also appear.
 7. Type "RUN" and press Return.  This runs the initialization program,
    which sets up the environment and displays the title.
 8. Type "CLOD NC1B" and press Return.  (Number Cruncher 1, program B)
 9. As before, press the disc twice to change "SET" to "GO" to "LOAD".
10. Wait until the cursor reappears again.  This will take a little
    longer to load.
11. Type "RUN" and press Return.

Now for the instructions.  This is meant to be played with two players.

First, type a target number between 20 and 100, using the ECS keyboard,
and press Return.

Wait until both boards populate, each a 6x6 grid of digits.  The bottom
half of the screen will begin to fill with purple cards, representing
the target value as a meter.

Both players share the left controller (the ECS BASIC interpreter only
reads the left controller).  Use the disc to move in any of four
directions, or a keypad key to jump between boards in the same position.
You can wrap around the edges of each board as well.  Hold the
disc/keypad until the cursor moves, then let go and give the controller
to the other player.

The meter will fill in your color based on the value of the digit you
moved to.  Finish filling the meter to win, or force the other player to
overfill the meter and lose.
__________

[Number Cruncher II]

 1. Launch jzIntv with Advanced Dungeons & Dragons and enable ECS.
 2. Select BASIC at the ECS menu.
 3. At the BASIC interpreter, type "CLOD NC2" and press Return.
    (That's Number Cruncher 2)
 4. "SET" will appear.  Press any direction on the disc.
 5. "GO" will appear, replacing "SET".  Press any direction on the disc
    again.
 6. "LOAD" will appear, replacing "GO".  Wait until the cursor
    reappears.  "NC2" will also appear.
 7. Type "RUN" and press Return.

How to play:

Use the keyboard to choose how many problems to solve.  For each
problem, you will be presented with eight indexes and their values.  A
random subset of values will be added together to make the Target
number.  The object is to figure out which values add up exactly to the
target.

Hold one of the keypad keys 0-7 on the left controller to select an
index until an arrow appears next to that index, pointing to its value.
Hold that number again to deselect that index, making the arrow
disappear.  Hold Clear to deselect all indexes.  Hold Enter when you
think you've solved the problem.

You will be notified whether you were right or not.  Press and release
the disc to start the next problem.  After all the problems, you are
presented with the number of problems you got right and the total number
of problems, plus the percentage.  Your final score is the percentage
multiplied by (the number of problems attempted plus 1).  Points are
deducted based on the amount of time taken, so I don't recommend playing
at a faster speed.

[Bomb Run I]

This one was originally recreated by Dave Harley.  As a result, it has a
filename different from what I've been using.

 1. Launch jzIntv with Advanced Dungeons & Dragons and enable ECS.
 2. Select BASIC at the ECS menu.
 3. At the BASIC interpreter, type "CLOD BMB1" and press Return.
    (That's Bomb Run 1)
 4. "SET" will appear.  Press any direction on the disc.
 5. "GO" will appear, replacing "SET".  Press any direction on the disc
    again.
 6. "LOAD" will appear, replacing "GO".  Wait until the cursor
    reappears.  "BMB1" will also appear.
 7. Type "RUN" and press Return.

Press any action key on the left controller to begin.  The screen will
be filled with color to draw the water and sky.  Use the disc to move
the boat left and right, and hold any action key to drop bombs on the
debris in the water.  Points are awarded based on accuracy after a
certain number of targets have passed by.
__________

[Bomb Run II]

 1. Launch jzIntv with Triple Action and enable ECS.
 2. Select BASIC at the ECS menu.
 3. At the BASIC interpreter, type "CLOD BR2A" and press Return.
    (That's Bomb Run 2, program A)
 4. "SET" will appear.  Press any direction on the disc.
 5. "GO" will appear, replacing "SET".  Press any direction on the disc
    again.
 6. "LOAD" will appear, replacing "GO".  Wait until the cursor
    reappears.  "BR2A" will also appear.
 7. Type "RUN" and press Return.  This runs the initialization program,
    which sets up the environment and displays the title.
 8. Type "CLOD BR2B" and press Return.  (Bomb Run 2, program B)
 9. As before, press the disc twice to change "SET" to "GO" to "LOAD".
10. Wait until the cursor reappears again.  This will take a little
    longer to load.
11. Type "RUN" and press Return.

How to play:

This is a single-button game.  Hold any action key on the left
controller to drop a bomb on the terrain below.  Clear the terrain with
your bombs as your plane passes overhead, a little lower with each pass.
Reach the ground with all the terrain cleared to advance to the next
level.  Try to complete all ten levels without crashing into terrain.
