IPRI software snapshot
This is the first release of the completed IPRI firmware code base as of version 1.00. All functions are present but the
debugging may not yet be complete - it is certainly "good enough" though. Due to 'blowing the budget' on the original choice
of CPU (the at90s4433) there are two variants. A debug version that is small enough to run on the ICE200 emulator targeted
at the at90s4433 and the full version which runs on the atMega8.
More info on the IPRI project page
- Update now with read only version number and better documentation is now available here
- The first complete release of the IPRI firmware for the atMega8 CPU is now here
Instruction packs
- A copy of the web site pages with all the information on the
FEP box
- A copy of the web site pages with all the information on the G4XYW modem
version 3.6
- A copy of the web site pages with all the information on the G4XYW modem
version 2.8
Webconvers
- The tarred and compressed PHP scripts for this web server gateway to convers
package are at version 2.0 after a major rewrite for the latest version of
PHP and it's here
- Older versions here 1.4
, and
1.5
FEP modification
- The complete FEP source code and executable EPROM image in Intel hex format
now available for the ASxxxx series assembler/linker is here
- This PCB is for the configuration and KISS port on the FEP box, using the
async ports on the CPU chip itself. Its a basic TTL to V24 converter making
use of the onboard 16pin DIL connection that gives access to these ports.
The Postscript files for the PCB and overlay are
here
- The patch program for the config EPROM, written in QBASIC and including
a DOS executable and a template file to be edited is
here . This now reflects the defaults in
the firmware below.
- The old version of the FEP code from May 2000 (EPROM image only)
JNOS for DOS
- The zip archive file tvipinst.zip
- The readme file from the archive
- The node executable version of JNOS "tvipnode.zip" for the Arkwrights Till with
extra SCC and Netrom support. This zip file contains the config file as well as the executable so you
can see what has been compiled into it.
The Regenerative Repeater Controller
- Assembler file as plain text This is not
supplied as an Intel HEX file as it MUST be customised
- Zipped up assembler and include files
- PCB files - the schematic is not yet
complete but since its the
same as a modem without the analogue section...
The G4XYW modem CPU code
- Minor bugfix release (4.06)
dual speed
source, documentation and hex files.
- Major bugfix/new functions/better FIR version (4.05)
dual speed source, documentation and hex files.
- Last release (3.16) of the FIR TX source
and hex files
code, hex executable code and a choice of FIR coefficients
- Previous releases
- Suitable assemblers are:
- Suitable programmers include the one from BA1FB
- AVRP modded to handle AVRA created files by ZL3ROB. A Windoze Command line Executable (zipped) is available
here
The G4XYW modem PCB and schematics
The PCB details have been exported from the PCB design tool as
PostScript files and should therefore accurate and not suffer from
pixelation problems trying to use the web page graphics. The scaling
should be correct but can be checked by using the pin spacing on the ICs
as this will always be 0.1".
- V3.6 PCB files in Postscript format
- V2.8 PCB files in Postscript format
- V3.6 circuit diagram in Postscript format
- V2.8 circuit diagram in Postscript format
The G4XYW modem async drivers
Those so far available are:
- XYWBPQ.EXE - BPQ external
hardware driver for DOS
- XYWPKT.COM - packet driver for
*NOS DOS systems
- XYWAX25.COM - Ethernet card
simulation driver
- SV2AGW
- packet engine driver for win95 and win98
- xywmodem - async driver for Linux kernel AX.25
using ax25-utils package for 2.0 kernels and the new ax25lib for 2.2
kernels. This package is still early Beta - see enclosed
README file
- 2.4 xywmodem - async driver for Linux kernel AX.25
using ax25-utils package for 2.0 kernels and the new ax25lib for 2.2 and 2.4
kernels. This package is now much improved by YO2LOJ who has added lots of documentation.
Details of each driver can be found on the drivers page
or download and read the source :-))
The Sources
for these drivers can be found
here.
UKisms for JNOS
These mods, by ZL3ROB, are
an attempt to make the popular JNOS DOS/Linux program to be compatible with UKNOS
and to make the transfer of bulletins transparent between IP and AX25
networks.
They are supplied as a set of files which are unpacked over the top of (and
hence overwriting) the original sources from the
JNOS home page
Only the latest version (1.11e) is held here,
older versions can be downloaded from ZL3ROB's web site
