I have a Rotal RTA1320, which is apprantly Dynalink manufactured.
Firmware
I've replaced the existing with http://www.dynalink.com.au/firmware.htm?prod=RTA1320 from 7.2007. Didn't need to restore the configuration xml since it just kept the old values (haven't rebooted yet).
cormain in australia has all version, the 2.2 that wizardwiz claims is the best, my currently installed 3.30j, and 3 in between.
This talk on fresh convinced me to try it out. Happily it seems to be ok (12 minutes after the upgrade, 2007-10-31 00:29:05).
Rotal's homepage is less helpful, not providing any firmware links, not even stating that the machine is running linux. From the telnet connection:
