Turbo-Plus VI.41 16-bit Installation Guide
INTRODUCTION
This Installation Guide describes the procedure for
generating a configuration of Turbo-Plus in a system which
includes 16-bit boards.
For information on the 8-bit installation refer to the 8-
bit Installation Guide to Turbo-Plus. For information on using
the package refer to the User *s Guide to Turbo-Plus. That
document includes an overview of the package and instructions on
using each command.
Turbo-Plus is designed with the ability to be patched to run
on systems with different search drives. Since it needs to know
what drive this is it is set up as a patchable parameter. Thus
most of Turbo-Plus’s modules are distributed as relocatable (.0)
files so that parameters may be ’plugged in’ in the installation
procedure using the TurboDOS symbolic patch facility described in
the Configuration Guide to TurboDOS.
Section 2 of this guide briefly describes all of the modules
sent as part of the 16-bit Turbo-Plus package and explains where
on the system they should be placed.
Section 3 describes the installation procedure for
generating a customized version of Turbo-Plus excluding the
background batch processor which involves some extra steps.
Section 4 describes the installation procedure for the 16-
b t. background batch processor.

Turbo-Plus VI.41 16-bit Installation Guide
Overview
Turbo-Plus makes extensive use of the TurboDOS User Defined
Function (TurboDOS call 0x29) and follows the USBSUP calling
protocol outlined in your TurboDOS 1.41 update notes and in
Appendix G of the 8-bit installation manual. Therefore. if you
wish to add your own functions with this call it is imperative
that you also follow the USBSUP protocol which has been adopted
by Software 2000 as the standard TurboDOS method.
Serialization
Each copy of Turbo-Plus is serialized to be run only on a
■no T> + ■? /*ii Tot» T ii n na no + ■? nrf piro + am •Pin a eanl o 1 rmmVi a t*

coincides with that of the operating system on which it is to be
run. None of the modules in Turbo-Plus will run on any system
with a serial number different that its own.

Turbo-Plus Modules
16 bit Turbo-Plus will arrive on two sides of one CP/M
format single-sided single-density diskette. Side one contains
all of the relocatable modules; side two contains .DO .GEM and
.PAR files used to generate your Turbo-Plus installation.
Program Modules
Side one contains three types of files:
1) Relocatable program files:
Those files which constitute the main bodies of the
Turbo-Plus utility programs.
2) Relocatable subroutine files:
Those files which contain subroutines called by the
programs above.
3) System function files:
Files containing extensions to the normal set of
TurboDOS operating system calls which must be genned
into the operating system.
Side two contains all of the supporting files used for
generating your installed version of Turbo-Plus. This includes
.GEN and .PAR files for your programs auxiliary data files two
installation .GMD files and .DO files referenced by the install
programs.

Instal1ing Turbo-Plus
Generating executable programs
Before you begin your Turbo-Plus installation make a backup
of tbe distribution diskette(s). If you received Turbo-Plus on a
single TurboDOS format disk you may run the install procedure
directly from that disk. If not you must copy the first two
disks onto any user area on the system other than user zero of
the search drive.
To customize Turbo-Plus to your system configuration
execute the INSTALL command. This program will prompt you for
your TurboDOS version number system search drive and the drive
which currently contains your system boot disk (do not include
the colon after the drive letters); all of the necessary .CMD
files will be generated and moved down to the search drive.
Then all of the .HLP files should be moved from the distribution
disk to user zero of the search drive. During execution of the
INSTALL process it is very possible that certain stages will
return with system error messages such as ’File not found5. This
is due to the fact that the procedure must make sure that if any
of these programs were already present in an older version they
are deleted. Thus if the programs were not there trying to
delete them will yield error messages.
Note: If you do not have a system search drive you must
still give some drive parameter to be used by Turbo-Plus as the
dri^e on which to maintain all of its files.

Turbo-Plus VI.41 16-bit Installation Guide
System Generation
Before Turbo-Plus may be brought up it is necessary to
generate a new operating system. You should start with the .GEN
and .PAR files which you are currently using for both your
slave(s) and your master but some additions will be necessary.
Generating a new system master
The following changes must be made to the .GEN file for your
system master (usually STDMASTR.GEN or OSMASTER.GEN). Using your
system editor insert the following lines.
NETREQ
MSGFMT
NETFWD
USRSUP
TPLUSM
If you have the ability to use the TWX and RESET commands
it is recommended that you use modified circuit drivers. Many
existing circuit drivers have already been modified
appropriately; if your dealer says that yours has not been a
revision will be necessary. There should be no change made to
the master circuit driver and the source for your slave circuit
driver should be changed following the instructions in Appendix
A.
If you are running a multi-circuit system one patch line
will be required in your master .PAR file. For a full
explanation of this patch point refer to Appendix B in the 8-bit
installation manual.
Figure 3.1 shows a sample OSMASTER.GEN file prepared for
Turbo-Plus.

Generating new slaves
Next in your slave .GEN files add lines containing USR8UP
and TPLUSS following the hardware initialization module. You
should also include NÊTFWD and NETSVG immediately after the line
for STDSLAVE. Also to optimize the performance of the TWX
command you need a special console driver modified circuit
drivers and a separate module to handle the shift-in shift-out
produced by TWX.
If your standard console driver is C0N96 you may use the
C0N96TP driver provided with Turbo-Plus. (To do so simply
replace the C0N96 line in your .GEN file with C0N96TP). If not
you should modify your driver such that before every console
output it performs a WAIT operation on the global semaphore:
TWLOCK and after each console output it performs a SIGNAL
operation on the same semaphore. It should also allow for a
character to remove the TWX message from the 25th line of the
screen by calling the external routine TWXRST when this
character is received. C0N96TP uses the ESC character by
default and if there is no message on the status line it allows
the escape to passed through normally. Figure 5.5 shows the
C0N96TP driver which may be used as a guideline.
Furthermore for those of you using TWX and RESET your
circuit driver may require modification. Consult appendix A for
the necessary changes.
The second module necessary for TWX handles the placing of
TWX messages on the screen without interrupting normal console
input/output. If you are using a Televideo terminal you may use
the TWXTV module which places all received TWX messages on the
terminal status line. For any other terminal you may use the
TWXNUL module which simply prints each line at the current
cursor position followed by a carriage return-line feed
sequence. A source listing of this module is provided and
explained in Figure 3.6 in case you wish to modify it for your
specific terminal. Modification may be done either by writing
your own driver our patching TWXNUL in the slave .PAR file.
Figure 3.4 shows a sample slave .GEN file and figure 3.3
shows the corresponding .PAR file.
Once all of these changes are complete you are ready to
generate the new master and slaves using the GEN command in the
usual way. (Refer to the TurboDOS configuration Guide.) Once all
of these steps are done copy the newly created .SYS files down
to user zero of your boot disk and Turbo-Plus will be ready to
come up.
