Installing the Spectranet firmware
==================================
Installing the Spectranet firmware on Fuse is slightly more complicated
than on a real machine, mostly because Fuse's emulation doesn't support
DHCP. These instructions are correct as of 2012-01-26 - if you're using
a later firmware than this, things may have changed slightly.
The first thing you will need to do is to obtain a copy of the
Spectranet installer as a .tap file (or similar). You can find installers
at http://spectrum.alioth.net/doc/index.php in the Downloads section, or
you can see below for instructions for building the installer from
source. A number of Spectranet-enabled folks hang out in the #zx channel
on the Coldfront IRC network (irc.coldfront.net) - try asking in there.
Once you have a copy of the installer, start Fuse and tick the
"Spectranet" and "Spectranet disable" options from the Options /
Peripherals / General... dialog box. Once that's done, open the
installer file (use the Media / Tape / Open... command rather than File
/ Open... to prevent autoloading) and enter the following commands from
BASIC:
CLEAR 26999
LOAD ""CODE
RANDOMIZE USR 27000
The screen should turn blue and you'll see around 20 lines of message
appearing as the firmware is installed, starting with "Erasing sector 0"
and finishing with "Restoring page B", and you'll get the familiar
0 OK, 0: 1 at the bottom of the screen.
Now untick the "Spectranet disable" option in the Options / Peripherals
/ General... dialog box and reset the Spectrum. You should see a very
brief blue status screen, before the regular copyright screen appears
with some Spectranet information at the top - there should be four
status lines, starting with "Alioth Spectranet" and ending with the
Spectranet's IP address (which will be 255.255.255.255 at this stage).
If you see all that, trigger an NMI (the Machine / NMI menu option) and
you should get a white on blue Spectranet NMI menu with five options.
Select [A] Configure network settings - this should lead you to another
menu, which will scroll of the top of the screen; don't worry about this
for now.
You'll now need to set various options:
[A] Enable/disable DHCP - select N
[B] Change IP address - enter the IP address of the machine you are
running Fuse on.
[C] Change netmask - enter the appropriate netmask for the IP address
you selected above. If that doesn't mean anything to you, try
255.255.255.0
[D] Change default gateway - enter the appropriate gateway address. If
you don't know any better, enter the IP address of your router.
[E] Change primary DNS - enter the address of your DNS server. If you
don't know any better, use Google's public DNS server, 8.8.8.8.
There is no need to change options [F] or [G], but do select:
[H] Change hostname - enter a hostname for the Spectranet-enabled
machine. It doesn't really matter what you enter here - it's mostly
useful just to replace the junk default name so you can see what
you've entered for the other settings.
Your screen should now look something like this:
Current configuration
=====================
Use DHCP : No
IP address : 192.168.000.002
Netmask : 255.255.255.000
Default gateway : 192.168.000.001
Primary DNS : 192.168.000.001
Secondary DNS : 255.255.255.255
Hardware address : FF:FF:FF:FF:FF:FF
Hostname : fuse
<menu options>
If every looks correct, select [I] Save changes and exit (you'll see a
brief "Saving configuration..." message) followed by [E] Exit, at which
point you'll be returned to BASIC. Reset the Spectrum again and you'll
see the same four line status display, but this time with your IP
address on the last line.
Congratulations! You have now installed the Spectranet firmware. To save
having to go through all that every time you start Fuse, save a .szx
snapshot at this point, and load that in every time you want to use the
Spectranet.
Compiling your own Spectranet installer
=======================================
If you really need to compile your own copy of the Spectranet installer,
here's a brief guide. It's very Debian-specific, but should be easily
adaptable to other Linux (or maybe even Unix/BSD-like) distributions.
First, install a few tools:
$ apt-get install subversion make binutils-z80
Get the latest Spectranet code:
$ svn co http://svn.alioth.net/svn/spectranet/trunk spectranet
Build the installer
$ cd spectranet
$ make
Lots of output should now appear, after which your installer should be
created as installer/installer.tap.
