Release Notes for OMEn Version 2.46, June 3rd, 1994
(C) 1994 Esquimalt Digital Logic Inc.
Message from the president
Welcome to the first release of the Open Multitasking Environ-
ment, OMEn. It runs on Atari series computers. We plan on OMEn
becoming a major operating platform, and you are among the first to
view it.
Future releases for Mac, Amiga, and PC (with 680x0 OMEn
processor card) will run the same OMEn software as the Atari does.
The accompanying feature sheets ("OMEn Key Features" file)
outline the major unique features that make OMEn a really special
system, and there are plenty of lesser innovations you will discover
as you explore the system and its software.
OMEn is the first operating system to really integrate software
at the system level. It is a "Componentware" environment where
smaller software applications can specialize in doing one thing well
instead of having to do a number of things in one package.
Although OMEn is not yet perfected in this version, it will
improve over time. OMEn is the only system that makes bugs less
damaging: control of the computer and work in progress is seldom lost
if a program bombs.
The OMEn system uses less memory than any other. It was written
in compact, fast, assembly language. It loads faster, will run off a
floppy, and leaves more space for programs and data. It will
eventually run on many types of computers, and even on certain game
machines and embedded controllers where a bulky system wouldn't fit.
We hope you will find OMEn to your liking and confidently expect
there will be many third party software houses writing or porting
interesting and useful OMEn software for entertainment, business,
music, industrial/home control & security, data acquisition,
multi-media, graphics and more.
Sincerely yours,
Craig Carmichael, Pres.
Esquimalt Digital.
BBS (Archived) Version
The notes below refer to file names which are longer than 8
characters (up to 14) and may be in upper and lower case, using
OMEn's DOS/GEM upward compatible filing system. However, when disk
files are archived (or copied) using GEM/TOS/DOS software, the
filenames shown are chopped off to 8 characters and made into upper
case, so the names don't quite match these notes. The fourth
character of the file extension and the version number are likewise
lost.
When many of the files are opened, there will immediately be a
'u' next to them, indicating they should be 'updated', and the
complete (up to 47 character) OMEn file name will appear. The 'u' may
be ignored. When files are updated, the 14 character file name is
restored in the directory. For files where the file's header wasn't
saved with the file, the 8 character name remains and there is no
'u'.
There was also an unknown problem in archiveing the "Text Ed"
binder containing the Text Ed program and its directory icons:
Text Ed wouldn't run after expansion and the file sizes were wrong.
The binder had to be dropped, and Text Ed placed as a program file in
the "Software" folder.
Getting Started
Startup
Like any Atari program, OMEn is started by double clicking on
the OMEN246D.PRG icon or name in a GEM directory window.
If you boot off a hard drive, then either "Fonts" and "Settings"
folders must be on Drive C, or a floppy disk must be in Drive A.
Otherwise the system crashes while booting up. OMEn checks drive C
first for these folders, then if it doesn't find them (or doesn't
find a Drive C), it searches on drive A.
On a Falcon, you must boot from an ST compatible video mode. The
mode can then be changed as desired from the Atari Big Screen video
manager in the System folder. (This was just discovered as we
normally boot our Falcon in ST-Medium for other reasons.)
Note: GEM/TOS on the Falcon seems to have trouble opening
folders/files with lower case in their names. ST and TT have no such
problem, and there is no problem on any machine while running OMEn.
Finding Disk Software
The file management system is not complicated, but it does need
a bit of introduction.
First, click means just one click: there is no double clicking
with OMEn.
Second, you have to be very careful not to move the mouse while
clicking. If the mouse moves, the system generates "dragging"
messages instead of "clicking" messages, and what you expected won't
happen. (We hope to improve this in the future.)
Finding the disks and programs on the disks:
* Click on DIRs at the top of the main window. This opens
a directory window. The window starts up looking at the
Memory folder, which is the root directory for the
whole system.
* Click on Disk Drives. This is the root folder for all
the GEM/DOS drives and disks in the system. A list of
available drives is shown as folders. Drives don't have
icons on the desktop.
* Click on the drive with the OMEn software. It opens to
show the files and folders on the drive. Programs that
you can run are shown with a "running animal" icon.
* Click on a program to start it up.
Getting out of a folder.
To exit a folder to its parent folder, simply click on the name
of the current folder, which is just above the list of files (on the
second line of the directory window). On a colour screen, this name
is on a blue background.
To exit out from several levels of folders at once, click on the
name at the very top of the directory window. If you are anywhere on
a drive, it will exit to the Disk Drives folder showing the list of
drives. If you are already in that folder, it will exit to the Memory
folder.
Since the Memory folder is the root folder, there is no way to
exit outwards from it and clicking on this name will have no effect.
The other folder shown in the Memory directory when you boot-up
OMEn (besides Disk Drives) is System. It contains software which is
always placed there when OMEn starts up.
Copying Files
Files in the Memory folder are not saved on a disk; they will
disappear when you exit from OMEn or turn off the computer. This
applies as well to any new files copied into the System folder, which
is also in memory.
To copy a file:
* Two directory windows are required. If only one is open,
click again on DIRs to open a second one.
* Get to the folder where you want to copy the file to in
the second directory window. (You have to be viewing
inside that folder, seeing its files.)
* Drag the file from the first directory window to the
second one. It will be copied.
Copying Between Floppies; Changing Floppy disks
To copy files between disks with just one floppy drive:
* Copy the files into the Memory folder from the first
disk.
* Swap disks. When you swap floppies, exit from Drive A
in the directory window (back to Disk Drives, see above)
and then re-enter Drive A to open (read-in) the new disk.
* Copy the files from Memory back to the new disk.
* Delete the files from memory if they aren't to be used.
To select several files, click on each one with the RIGHT mouse
button.
If a disk has a "volume label" (a name), this name will be shown
instead of "Drive A" after the disk is opened.
OMEn handles any Atari or MS-DOS disk format properly, including
5-1/4" disks. If you are using a 5-1/4" external drive, you should
run Atari Disk Drives I/O port in the System folder (click on it like
a program) and set the "Floppy Seek Speed" to 6 or 12 milli- seconds
instead of 3 milliseconds, which is too fast for most 5-1/4" drives.
Starting Text Ed Program to Read/Edit the TEXT Files
* Locate Text Ed in the Software folder on the disk.
* Click on it to start it running.
* Locate the document to be opened.
* Drag the document from the directory window to the
File button in the Text Ed window. Text Ed will read
it off the disk and open it.
Note: The Text Ed you see in the Software folder is a binder
directory called "Text Ed". It contains the Text Ed program and three
different sizes of icons also called Text Ed for different screen
resolutions.
A binder is similar to a folder except that it doesn't open to
show the files. Instead, it works as if the entire binder with all
its files was one file. (To open it
