China DOS Union

IMG.EXE is just ready to use, thanks to the LZ owner for sharing.

I didn't go to download, but can commemorate.

Searched, found this:

800 II v1.80; Bios enhancement - many new diskette formats

In the era when 5.25-inch floppy disks were popular, 800-II could format a 360K capacity disk into 800K capacity in a high-density drive. It is a TSR program. After running, use the DOS FORMAT plus parameters to increase the number of tracks to 83 and the number of sectors to 10.

It can also increase some space for 1.2M large floppy disks.

There is also a similar tool called FDREAD FDFORMAT

Not just nostalgia, qe is still in use now.

Essential Tools for DOS Software

　　There were some very good tool software and some classic small games in the DOS era. The gaming intelligence level of these games is by no means inferior to many current 3D big-production games. Since people in the DOS era mostly used floppy disks as storage media for communication, these programs, even if stored on CDs, are somewhat different from the familiar storage methods today. To access the DOS treasure trove, you should use the following 5 tool programs:

　　HD-COPY.EXE for floppy disk copying, formatting, and IMG image file creation and restoration.


　　IMG.EXE the most convenient image file restoration software.

　　ARJ.EXE for file compression and decompression.

　　PKUNZIP.EXE for zip file decompression.

　　RESTORE.COM for restoring backed-up files.

　　The usage of HD-COPY has been described above. IMG.EXE is compiled for HD-COPY and another copying software called DDUP. HD-COPY can completely create an.IMG image file of a floppy disk for storage, but when using it, you must again use HD-COPY to transfer the.IMG image file to a floppy disk. With IMG.EXE, this trouble is omitted. IMG.EXE directly opens an area of the size of a floppy disk capacity in memory, simulates a floppy disk, and restores the.IMG image file to this simulated floppy disk, and then the user can install the software on the simulated floppy disk to the hard disk. And IMG.EXE uses the hotkey "Ctrl+Alt,S,D,X" for switching, so multiple floppy disks can be processed continuously. Using "Ctrl+Enter" can clear IMG.EXE from memory. If you see a file from the DOS era with the extension.IMG or.DDI, then this is mostly a floppy disk image file, and IMG.EXE can be used to complete the installation.

　　If a DOS file has the extension.ARJ,.001,.002, etc., then this is a compressed file created with ARJ.EXE, and it can be decompressed with it. You can call up the usage help through the DOS command "ARJ /?".

　　Similarly, PKUNZIP.EXE can be used to restore compressed files with the.ZIP extension.

　　RESTORE.COM is used to restore files backed up with BACKUP. The BACKUP command is not directly compatible between different DOS versions, but a version can be specified. Now we don't need to understand these. Just note that using a higher DOS version and RESTORE.COM is fine, and it is backward compatible.

Something that I've been using all the time, it's really useful.

These software are not particularly old software. However, it's good that you still have them saved. Hee-hee. If you have the PM software, you're just being foolish.

No translation needed as the text is in Chinese but the content is about 800 not being used now and missing it, and the translation instruction is to translate from Chinese to English but here it's already in Chinese. Wait, no, wait. Wait the original is "800现在不会有任何人用了，怀念一下" which needs to be translated to English. So it should be "No one uses 800 now, just missing it."

That's amazing. Where did you find it?

Miss everyone!

800 seems to be a floppy disk expansion program, but it seems useless now.

Q, not bad, I used it before, now relive it... really good! Haha!
