A little bit of casual coding.

Generate a PDF that has the correct layout and size for the SPA500's keymap.

It is 155mm long, and 47mm wide. This means that it should be 23.5mm to the middle line, and each of the 16 buttons should be 9.6875mm in height.

Note you need php-fpdf to use this. You can run this script and view the output here: http://hipbx.org/sample/genspa500.php

After printing it out, and putting it in a SPA500, this is what it looks like!

<?php
$buttons = array("Rob Thomas <500>", "Do Not Disturb", "Day/Night switch", "Xorcom <+972 4 9951999>", "Fred's Mobile <0402 077 155>", "dbond <756>",
 null, null, null, "Other", "Ford Prefect <+44 1837 223 224>", "Divert to Mobile <*450402077155>", "Blah Blah <123>", "I'm getting bored <of typing these>",
"But I need more", "I don't need to", "put numbers <123>", "In all of them <though>");
require('fpdf/fpdf.php');
$pdf=new FPDF('P', 'mm', 'A4');
$pdf->AddPage();
$pdf->SetFont('Arial',,16);
$pdf->Cell(40,10, 'SPA500 Keypad Layout for 999 (Username)');
$pdf->SetFont('Arial',,8);

$xpos = 10;

# Just draw the boxes
for ($i = 0; $i <=31; $i++) {
       $bg = $i+1;
       if ($i >= 16) {
               $xpos=33.5;
               $bg--;
       }
       $pdf->SetFillColor("192");
       $pdf->SetXY($xpos, ($i%16)*9.6875+30);
       $pdf->Cell(23.5, 9.6875,"",1,0,"C",($bg%2));
}

$xpos=10;
# Now, fill the details in.
for ($i = 0; $i <=31; $i++) {
       if ($i >= 16) {
               $xpos=33.5;
       }
       $pdf->SetXY($xpos, ($i%16)*9.6875+30);
       # Does it have a < in it? If so, that should go on the second line.
       if (preg_match("/(.+)<(.+)>/", $buttons[$i], $matches)) {
               $pdf->Cell(23.5, 9.6875/2, $matches[1], 0, 0, "C");
               $pdf->SetXY($xpos, ($i%16)*9.6875+30+9.8675/2);
               $pdf->Cell(23.5, 9.6875/2, $matches[2], 0, 0, "R");
       } else {
               $pdf->Cell(23.5, 9.6875,$buttons[$i], 0, 0, "C");
       }
}

$pdf->Output();
