- De-jet v1.00
-
- De-jet is an assembly language program to take the game 'Jet', by Sublogic
- Corporation, and put it in a DOS "EXE" file. If your copy of Jet isn't just
- like my copy this program will not work. I am only aware of one Jet version and
- this is the Jet which this program was designed around.
-
- Several extensions will be added by the De-jet program. These include the
- EXIT TO DOS option on the main menu, preservation of the original command line
- functions 'h,e,m' or their upper case equivalents, and the inclusion of the
- extended situations data for all of the options. The extended situations data
- are those sectors which need to be loaded if one chooses an option such as
- 'Free flight, level ?, F-16'. These were originally not loaded with the Jet
- game but were loaded as required. They now will exist as data at the end of the
- Jet.exe file and will be copied in as required.
-
- Room has been left in certain places in the EXE file for the addition of
- future options as demand dictates. If you would like to see a supervisor key
- added; i.e. the jet game frozen, a second copy of command.com loaded and
- executed, and on EXIT the jet game resumed from the same place in flight; then
- let it be known as public E-mail on PCUG in Atlanta, Ga. # 404-433-0062 .
-
- This program is involked by typing 'de-jet <drive>'. The drive spec is the
- drive to which the Jet.exe file will be written. It will use the current path
- of the specified drive. It will use any valid dos drive installed. The JET disk
- will be placed in drive A for reading and may only be placed in A. You may use
- drive A as the specified drive if you wish, you will be prompted to change
- disks as required. You will need about 90k of free memory to run this program.
- I've thus far run De-jet and the Jet.exe file it creates on a PC and and AT w/
- an EGA card. I do not know if a 128k Jr. will be able to run De-jet.
-
- e.x. DE-JET d: ...will write JET.EXE to drive d: in the current path.
-
- De-jet will work if drive A and B are the same drive and drive but both de-jet
- and dos will prompt you to change disks, don't worry I'll fix it later.
-
- The resulting file should be 86,016 bytes in length. All command line
- parameters should still work. i.e. h or H for Hercules Card, e or E for the
- EGA card, and m or M for the EGA w/ a monochrome monitor.
-
- If you wan't the source then leave a message on the board and I'll put
- it up. Its about 30k long. If you find a bug in this program or if you find
- it doesn't work on your copy of Jet then please leave mail.
-
- One other note of interest; don't expect the Jet.exe file to run under a
- multitasking operating system. Jet installs many of its own interrupt vectors
- over those of BIOS. One is int 9 for keyboard control and that change alone
- should rule out any multitasking or resident programs being called while
- Jet.exe is running. This problem could be solved however I'll leave that to
- subsequent versions of De-jet.
