- PROGRAM EMU VER 1.00
- COPYRIGHT (C) BY VIDEO TECHNOLOGY COMPUTERS 1987
-
-
- COLOR EMULATION ON MONOCHROME DISPLAY
-
-
- The program EMU.COM is a utility that enables many CGA software and games to
- run with monochrome graphics hardware and use monochrome monitor as the
- display.
-
-
- There are three valid parameters for the program :
-
- 1. The COLOR Parameter
-
- EMU COLOR[ENTER]
-
- This parameter enables you to run CGA software and games that require DOS.
- Activated with this parameter, the EMU program will first put the display
- into 80*25 color emulation mode and then exit to DOS. You are then free to
- run any CGA software and games from the DOS prompt.
-
- 2. The BOOT Parameter
-
- EMU BOOT[ENTER]
-
- This parameter enables you to run CGA software and games that require system
- resetting to boot up. Activated with this parameter, the EMU program will
- first put the display into 80*25 color emulation mode, and then prompt you
- with the following messege :
-
- Insert your boot disk into drive A
- Press any key when ready
-
- After you have put the CGA software or game diskette into drive A and press
- a key, the EMU program will reboot the system.
-
- 3. The MONO Parameter
-
- EMU MONO[ENTER]
-
- This parameter enables you to go back to normal monochrome mode display.
-
-
- In addition, there is a HELP MENU when you simply type EMU[ENTER].
-
-
- In using this utility software, several things are to be noted.
-
- First, the frequency of the video signal generated for the CGA emulation may
- be a bit different from the normal frequency for the monochrome display. Thus,
- you may have to adjust the VERTICAL HOLD knob of your monitor to get a stable
- screen.
-
- Second, in 80*25 color emulation mode, you will find that there is no cursor
- on the screen. This is due to the fact that the cursor is a hardware
- generated feature, and since no access to CGA hardware is available, there
- can be no cursor.
-
- Third, when exiting CGA software and games, please use legal methods provided
- by the software, and not illegal breakout like CTRL C. Otherwise, there is no
- guarantee that the system can be returned to normal monochrome mode by
- EMU MONO. The system may simply hang up.
-
- Fourth, please don't use monochrome graphics software when in emulation mode.
- The system may hang up and require a reboot to start again.
-
-
- Due to the large amount of CGA software and games written, and the diversed
- coding practices of progammers, there can be no guarantee that all CGA
- software and games can be run. However, we have try our best to provide
- compatibility to as many CGA software as possible and we hope you will find
- it convenient to have this utility with you.
