Cool, thanks :)

By the way, some of the terminals given away are monochrome.  There are
two types: the 8-bit colour ones and the mono ones.

To tell which you have, take a look on the side or bottom of the terminal
unit, and check the model number.  If it ends with a "C" (mine is a
XP215C), it's a colour terminal, however if it's a mono, the model number
will end with an "M" (a friend's terminal has a model number "XP214M").

Ok, my knowlege of how to manage fonts under X is a little above zero,
however, I _can_ share the following with everyone...

As with most terminals, you can have fonts living on your boot host,
served out via TFTP or NFS.  The X terminal setup software should allow
you to set the paths in which the terminal hunts for the fonts.

As well as this, the Tek X terminals also allow you to specify a remote
font server (e.g. xfs).  The syntax to do this is "<trans>/host:port".
For example, "tcp/proton:7100" would point my terminal at my font
server running on "proton", my main box.

However, with NCBridge at least, it seems to be broken: the terminals
don't seem to want to retain the setting of remote font servers across
reboots.  I (and others) have tried fixing this, to no avail.  If anyone
knows anything, feel free to let us all know.

Oh, and another thing.  A really easy way to power up these terminals is
to use an existing PC power supply.  For ours at home, we took one out of
an old PC case that was about to be thrown out.  You can wire a cable like
so (excuse the outrageously bad ascii art).  Having a cable like this
saves you from having to butcher the cables on the power supply itself.

(Many thanks to Byron Crowe and the guy at Jaycar for this idea).

       The soldering might get a little tricky though.
   ** To get it to work properly, join the two black wires on the 
       hard drive power connector together.
   ** To use, stick the male HD power connector end to the PC power 
       supply, put the other end in your terminal, and your terminal
       (should) have power.
   ** Be careful with mains power supplies.  It might be a  bad
       idea to run a power supply without a load on it (i.e. your
       terminal). Byron's power supply made weird noises when we did this.

Again, I hope this helps.  Take it easy and have fun :)

- warmest regards,

Ben.
