I posted a copy of the Matchport firmware to our website at  
 
    http://www.surveyor.com/blackfin/matchport-6500GE.rom
 
To install, use tftp -
 
     tftp -i xxx.xxx.xxx.xxx put matchport-6500GE.rom W8
 
where xxx.xxx.xxx.xxx is the IP address of the Matchport.
 
If you get a connection error, you can run tftp interactively
 
localhost:~/Desktop/$ tftp xxx.xxx.xxx.xxx
tftp> connect
(to) xxx.xxx.xxx.xxx
tftp> bin
tftp> put matchport-6500GE.rom W8

You can telnet to the IP address of your Matchport on port 9999 and the setup menu will dump the version number.  Also, if you connect to the Matchport configuration menu via your browser, the version is shown in the upper right corner.  So if your Matchport IP address is 169.254.0.10, either
 
telnet 169.254.0.10 9999
 
   or
 
http://169.254.0.10
