Current status
|
|

|
|
^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
The xtrs port is not operational yet; some work still needs to be done.

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
|
|
|
|
|
|
2008-02-16 06:10:33 +08:00
|
|
|
An emulator for this computer is available to run TRS80 programs on a
|
|
|
|
|
linux platform (http://www.tim-mann.org/xtrs.html).
|
|
|
|
|
|
2008-02-23 22:26:46 +08:00
|
|
|
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.

The SDCC toolchain is available from http://sdcc.sourceforge.net/. All
|

|
|
|
testing has been performed using version 2.7.0 of the SDCC toolchain.

Configuring NuttX
|
|
|
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
ostest
|
|
|
|
|
This configuration performs a simple, minimal OS test using
|
|
|
|
|
examples/ostest. This can be configurated as follows:
|
|
|
|
|
|
|
|
|
|
cd tools
|
|
|
|
|
./configure.sh xtrs/ostest
|
|
|
|
|
cd -
|
|
|
|
|
. ./setenv.sh
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
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:
|
|
|
|
|
|
|
|
|
|
cd tools
|
|
|
|
|
./configure.sh xtrs/nsh
|
|
|
|
|
cd -
|
|
|
|
|
. ./setenv.sh
|
|
|
|
|
|
|
|
|
|
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:
|
|
|
|
|
|
|
|
|
|
cd tools
|
|
|
|
|
./configure.sh xtrs/pashello
|
|
|
|
|
cd -
|
|
|
|
|
. ./setenv.sh
|
|
|
|
|
|
|
|
|
|
Building the 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
|
