NOTICE
THIS IS NOT FREE SOFTWARE! If you paid a "public
domain" vendor for this program, you paid for the serv-
ice of copying the program, and not for the program it-
self. Rest assured that nothing ever gets to the
originators of this product from such a sale. You may
evaluate this product, but if you make use of it, you
must register your copy.
We offer several inducements to you for registering.
First of all, you receive the most up-to-date copy of
the program that we have--and we do update the product
on a regular basis. You also receive support for
COTDOS--which can be quite valuable at times. And
finally, we include a few utilities not included in the
evaluation package. Make no mistake however--we do not
"cripple" our evaluation software--our sample programs
are fully functional and complete.
REGISTRATION INFORMATION
The non-commercial single-user registration fee for COT-
DOS is $15.00 US. The commercial and multisystem site
fee is $50.00.

Major Credit Cards Accepted
Please indicate what product you are ordering and if you
have a requirement for 3.5" media. We normally ship
5.25" 360K diskettes, but we will furnish 3.5" 720K
media upon request. Orders placed outside of the U.S.
and Canada should include an additional $5.00 for air-
mail. We can accept U.S. funds only, please.

What is COTDOS?
COTDOS is a device driver which supports reading and writing of
MS-DOS diskettes from Apricottm series computers on PC XT- or
AT-compatible machines. Under DOS 3.2, the utilities FORMAT, DIS-
KCOPY and DISKCOMP are supported, as well as normal DOS read and
write operations.
To use COTDOS, your computer must be PC AT-, XT- or IBM Personal
System/2 compatible. Computers such as the Tandy 2000 or the
Zenith Z-150 are not suitable because of their relative incom-
patibility. Further, your computer must be equipped with either
a 5.25" high-density (1.2 Megabyte) or 5.25" "quad" density
drive, such as the Teac 55F. The diskette adapter on your com-
puter must match the diskette drive characteristics. That is, a
high-density drive must be used with a high-density adapter.
Many manufacturers, such as Western Digital, produce high-density
diskette adapters for XT-style computers, and these may be used
successfully with COTDOS. Currently, we support only the first
(or primary) diskette adapter in a system.
And finally, your computer needs to be running PC-DOS or MS-DOS
Version 2.0 or later. DOS 3.2 or later is preferable, but not
required. Version 2 DOS users may find that some COTDOS func-
tions, such as formatting, are not supported.
Installing and Using COTDOS
Installation of COTDOS is straightforward. First, find the file
CONFIG.SYS in the root directory of the disk that your computer
boots (loads DOS) from. It may be possible that you do not have
a CONFIG.SYS file, in which case the next few steps will create
one. If you are unfamiliar with the CONFIG.SYS file, take time
out now and read the section in your DOS manual dealing with it,
and in particular, the DEVICE= statement.
You'll need to add a line to CONFIG.SYS of the following general
form:
DEVICE=COTDOS.SYS /D:unit /F:format
This can be done with the program EDLIN which is supplied with
DOS, or with a text editor of your choosing. If you use a word-
processing editor, make sure that you indicate that CONFIG.SYS is
a nondocument file. If you didn't find a CONFIG.SYS, the above
line will be the only line in the file which is created.
The value of unit can range from 0 to 3 and represents the physi-
cal diskette unit to be used to read and write the Apricot dis-
kettes. If this unit is normally called A: on your computer,
then the value of unit is 0; if B:, then unit is 1. External
drives are generally units 2 and 3.
Page 1
The value of format depends on the type of diskette drive that
you're using. If it's a high-density 1.2 megabyte unit, then the
value of format is 1. If you're using a "quad" density drive,
such as the Teac 55F, then format is 2.
If /D:unit is omitted in the configuration line, unit is assumed
to be 1. If /F:format is omitted, format is assumed to be 1 also.
The last step is to copy the file COTDOS.SYS into the root direc-
tory of your system or "boot" drive. Finally, re-boot your com-
puter. If your computer is configured with a revision of DOS 3,
the following message will be displayed:
Apricot diskette driver, Copyright 1990, Sydex
All Rights Reserved.
Apricot DOS diskette unit x is accessible as drive y:
The letters x and y will take on values which depend on the con-
figuration of your computer.
If your computer is configured with a revision of DOS 2, the fol-
lowing message will be displayed:
Apricot diskette driver, Copyright 1990, Sydex
All Rights Reserved.
Apricot DOS diskette unit x installed.
In this case, the drive letter which is used to read Apricot dis-
kettes will generally be one greater than the last drive letter
in use before you modified CONFIG.SYS. For example, if drive C:
was the last drive on your computer, COTDOS will use drive letter
D:.
As an example of the whole process described above, suppose that
we wished to add COTDOS to a PC-AT "clone" which has one high-
density diskette drive and a hard disk. Our CONFIG.SYS file on
drive C: might look like this after we modified it using EDLIN:
FILES = 30
BUFFERS = 10
DEVICE = COTDOS.SYS /D:0 /F:1 (This line is added)
We then copy COTDOS.SYS to drive C:...
COPY A:COTDOS.SYS C:\
We then press the keys Ctrl, Alt and Del simultaneously to
"reboot" our computer. After the rebooting process has com-
pleted, the following message is displayed:
Apricot diskette driver, Copyright 1989, Sydex
All Rights Reserved.
Apricot DOS diskette unit 0 is accessible as drive D:
Page 2
We then find that Apricot diskettes placed in our A: drive can
be read and written if we refer to that drive as drive D:.
FINAL COMMENTS...
COTDOS was written in response to inquiries from customers who
had our CP/M diskette transfer package, but who had no way to
easily handle the Apricot DOS diskettes. We hope that this situa-
tion is now remedied. If you experience problems in getting COT-
DOS to work for you, or if you have questions about any Sydex
product, please give us a call.
