- Merlin is a simple memory resident (pop-up) game. The hot-key is
- CTRL-M. It works on both color and monochrome systems.
-
- Merlin is played on a three by three board and the object of the game
- is simple; all you need to do is clear the board. The numeric keypad
- is used to toggle the squares. Here is the layout:
-
- +---+---+---+
- | 7 | 8 | 9 |
- +---+---+---+
- | 4 | 5 | 6 |
- +---+---+---+
- | 1 | 2 | 3 |
- +---+---+---+
-
- Pressing a key will toggle certain squares on or off. The idea is to
- clear the whole board. Pressing the 1 key will toggle these squares:
-
- +---+---+---+
- | | | |
- +---+---+---+
- | X | X | |
- +---+---+---+
- | X | X | |
- +---+---+---+
-
- Likewise, any corner key toggles the four squares in the corner. Edge
- keys (2,4,6,8) toggle the squares on the edge. Here is an example for 2.
-
- +---+---+---+
- | | | |
- +---+---+---+
- | | | |
- +---+---+---+
- | X | X | X |
- +---+---+---+
-
- The 5 key toggles the central squares:
-
- +---+---+---+
- | | X | |
- +---+---+---+
- | X | X | X |
- +---+---+---+
- | | X | |
- +---+---+---+
-
- That's all there is to it. You can scramble the board at any time by
- pressing ENTER. Press ESCAPE to exit Merlin. Don't forget to set
- NUMLOCK if you don't have a dedicated keypad.
-
- I first saw Merlin several years ago on another computer. I had a
- lazy weekend to kill and I wanted to see just how small a memory
- resident version of Merlin I could write. The .COM file is only 383
- bytes although the program occupies about 1200 bytes of RAM due to the
- screen save buffer.
