WHAT IS DEBIAN-HAM
------------------
Debian-Ham is a 2 floppy linux distribution with tlf and cwdaemon installed.
This way you can get a feel of linux and tlf, a trlog-like clone which
can be used for contesting. Included is a basic shell, a tiny editor and 
network support. Debian-Ham should be able to run on low-end machines, my
test machine is a 386SX20 without co-processor and 8 MB of RAM.

INSTALLING THE FLOPPY IMAGES
----------------------------
Debian-Ham floppy disk images can be written to a floppy with dd if you use
linux: 'dd if=filename.img of=/dev/fd0'. On windows, use rawrite. On windows 
NT or windows 2000, use ntrawrite, see http://ntrawrite.sourceforge.net.
There is also a rawrite for windows XP, you need to search for it.
A lilo boot and minix root disk is available. You need both.

USING DEBIAN_HAM
----------------
Insert the boot floppy in your floppy drive and reset your PC (note:
enable booting from floppy disc in the bios, if it won't work). After
a while, the startup script will ask for the second (root) floppy.
At the login prompt, login as root (no password).

Support is included for 4 different network cards:
- ne1000/2000 (ISA)
- 3c509/579 (ISA)

You must setup the network by hand. If it works, add your ifconfig and route
commands to /etc/init.d/rcS, so they will be loaded the next time. 
Examples are included in rcS. You can use the network to connect to a 
dxcluster with telnet.

CW KEYER
--------
Cwdaemon provides keyer support (type 'cwdaemon -h' for help). A transistor
switch can be hooked up to your parallel or serial port to interface with 
your transceiver. The parallel port is the default keyer port. Here is 
the circuitry:

                                        ----o  CW out to TRX
                                       |
                                       |
                                       | C
                         1k       B | /
   SELECT IN      o----/\/\/\-------|/      BC547, 2N2222, etc.
   (pin 17)                         |\
                                    | \| E
                                       |
   STROBE         o--------------------
   (pin 1)


   GROUND         o-------------------------o  GROUND
   (pin 18)

For the serial port you can use the next circuit (DB9 connector):

                                          +---------+--------o CW out to TRX
                                         /          |
  DTR      4k7                      B  |/ C         |
   o------|===|-----+------+-----------|      BC547,|2N2222, etc.
(pin 4)             |      |           |\ E         |
                   ---    ---            \         ---
          1n4148   / \    | | 4k7         +        / \ 1n4148
                   ---    | |             |        ---
                    |     ---             |         |
 GROUND             |      |              |         |
   o----------------+------+--------------+---------+--------o GROUND
(pin 5)


CONTESTING
----------
You can edit logcfg.dat (in the /root directory) before the contest with
'edit logcfg.dat'. When finished, type 'tlf'. 
You have about 390k free on the root floppy to run a contest.
