Getting a TRS80 emulator and DOS disks
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
This port uses a vintage computer based on the Z80, the TRS80.
|
|
There's a main page describing the different models of TRS80.
|
|
See: http://www.trs-80.com
|
|
|
|
An emulator for this computer is available to run TRS80 programs on a
|
|
linux platform (http://www.tim-mann.org/xtrs.html).
|
|
|
|
Other emulators are available for other platforms.
|
|
See http://www.trs-80.com, click on the link Emulators.
|
|
|
|
TRSDOS, LDOS and other softwares are available at:
|
|
http://discover-net.net/~dmkeil/trs80/software/trs-dos.htm
|
|
|
|
Or you can get TRSDOS 1.3 and 6.1 from this site; it's included with the emulator.
|
|
http://discover-net.net/~dmkeil/trs80/model4.htm
|
|
|
|
The SDCC toolchain is available from http://sdcc.sourceforge.net/. All
|
|
testing has been performed using version 2.7.0 of the SDCC toolchain.
|
|
|
|
Loading an executable into xtrs
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|

|
|
|
|
Configuring NuttX
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
ostest
|
|
|
|
This configuration performs a simple, minimal OS test using
|
|
examples/ostest. This can be configurated as follows:
|
|
|
|
1) From a POSIX window:
|
|
cd tools
|
|
./configure.sh xtrs/ostest
|
|
2) From a CMD.exe window
|
|
setenv.bat
|
|
make
|
|
|
|
If this is a Windows native build, then configure.bat should be used
|
|
in step 1) instead of configure.sh:
|
|
|
|
configure.bat xtrs\ostest
|
|
|
|
The setenv.bat will need to be updated to include the PATH to the XTRS
|
|
hex2cmd program.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. See the
|
|
"Reconfiguring" section below for information about changing this
|
|
configuration.
|
|
|
|
2. The default setup for this configuration uses a windows native build.
|
|
See the section entitled "Reconfiguring for Linux, OSX, or Cygwin"
|
|
which will give you the steps you would need to do to convert this
|
|
configuration to build in other, Unix-like environments.
|
|
|
|
3. The current build requires ca. 3.2.1 SDCC.
|
|
|
|
nsh
|
|
|
|
This configuration file builds NSH (examples/nsh). This
|
|
configuration is not functional due to issues with use of the
|
|
simulated serial driver (see the TODO list).
|
|
|
|
This configuration can be selected by:
|
|
|
|
1) From a POSIX window:
|
|
cd tools
|
|
./configure.sh xtrs/nsh
|
|
2) From a CMD.exe window
|
|
setenv.bat
|
|
make
|
|
|
|
If this is a Windows native build, then configure.bat should be used
|
|
in step 1) instead of configure.sh:
|
|
|
|
configure.bat xtrs\nsh
|
|
|
|
The setenv.bat will need to be updated to include the PATH to the XTRS
|
|
hex2cmd program.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. See the
|
|
"Reconfiguring" section below for information about changing this
|
|
configuration.

|
|
which will give you the steps you would need to do to convert this

|
configuration to build in other, Unix-like environments.
|
|
|
|
3. The current build requires ca. 3.2.1 SDCC.
|
|
|
|
4. This configuration depends on configs/xtrs/src/xtrs_serial.c which
|
|
is incomplete. At compile time, the following symbols are undefined:
|
|
|
|
ctrl, baud, rs232_xmtisr, rs232_recvisr, ch
|
|
|
|
pashello
|
|
|
|
Configures to use examples/pashello for execution from FLASH
|
|
See examples/README.txt for information about pashello.
|
|
|
|
This configuration is not usable because the resulting binary
|
|
is too large for the z80 address space.
|
|
|
|
This configuration can be selected by:
|
|
|
|
1) From a POSIX window:
|
|
cd tools
|
|
./configure.sh xtrs/pashello
|
|
2) From a CMD.exe window
|
|
setenv.bat
|
|
make
|
|
|
|
If this is a Windows native build, then configure.bat should be used
|
|
in step 1) instead of configure.sh:
|
|
|
|
configure.bat xtrs\pashello
|
|
|
|
The setenv.bat will need to be updated to include the PATH to the XTRS
|
|
hex2cmd program.

|
|
Reconfiguring NuttX
|
|
^^^^^^^^^^^^^^^^^^^
|
|
|
|
These configurations all use the kconfig-frontends, mconf-based configuration
|
|
tool. To change this configuration using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt and
|
|
misc/tools/README.txt
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the reconfiguration
|
|
process.
|
|
|
|
Reconfiguring for Linux, OSX, or Cygwin
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
All of the z80 configurations in this this directory are set up to build in a
|
|
Windows CMD.exe shell. This configuration requires the MinGW host compiler
|
|
and severl GNUWin32 tools (see discussion in the top-level NuttX/README.txt
|
|
file).
|
|
|
|
These configurations can be converted to run under Linux (or Cygwin or OSX),
|
|
by modifying the configuration file as follows:
|
|
|
|
-CONFIG_HOST_WINDOWS=y
|
|
-CONFIG_WINDOWS_NATIVE=y
|
|
+CONFIG_HOST_LINUX=y
|
|
|
|
-CONFIG_Z80_TOOLCHAIN_SDCCW=y
|
|
+CONFIG_Z80_TOOLCHAIN_SDCCL=y
|
|
|
|
You may need to first manually change the CONFIG_APPS_DIR="..\apps" definition
|
|
in the .config file because the backslash may upset some Unix-based tools.
|
|
|
|
This configuration will require a recent version of SDCC (ca. 3.2.1) for Linux
|
|
or custom built for Cygwin (see below).
|
|
|
|
You cannot use the default setenv.bat in these Unix-like enviroments because
|
|
that is a Windows batch file. Use configs/z80sim/script/setenv.sh instead.
|
|
setenv.sh must include the path to the installation location of SDCC (probably
|
|
/usr/local/bin).
|
|
|
|
SDCC
|
|
^^^^
|
|
|
|
These z80 configurations all use the SDCC toolchain (http://sdcc.sourceforge.net/).
|
|
Source and pre-built SDCC binaries can be downloaded from the SDCC SourceForge
|
|
site: http://sourceforge.net/projects/sdcc/files/ . Pre-built binaries are
|
|
available for Linux, MAC OSX, and for Win32. Various SDCC options can be
|
|
selected with:
|
|
|
|
CONFIG_Z80_TOOLCHAIN_SDCCL=y : SDCC for Linux, MAC OSX or Cygwin (see below)
|
|
CONFIG_Z80_TOOLCHAIN_SDCCW=y : SDCC for Win32
|
|
|
|
SDCC versions 3.2.0 or higher are recommended.
|
|
|
|
Building the SDCC toolchain
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
You may also want to build your own SDCC toolchain. You might want to do this,
|
|
for example, if you are running under Cygwin and want a Cygwin compatible
|
|
SDCC toolchain.
|
|
|
|
The SDCC toolchain is built with the standard configure/make/make install
|
|
sequence. However, some special actions are required to generate libraries
|
|
compatible with this build. First start with the usual steps
|
|
|
|
download
|
|
unpack
|
|
cd sdcc
|
|
./configure
|
|
|
|
But before making, we need to apply a patch to the SDCC 2.6.0 source
|
|
so that the z80 assembler can handle long symbol names
|
|
|
|
Apply sdcc-2.6.0-asz80-symlen.patch
|
|
cd sdcc/device/lib
|
|
|
|
Then make the SDCC binaries
|
|
|
|
cd sdcc
|
|
make
|
|
|
|
and install SDCC:
|
|
|
|
sudo make install
|
|
|
