Might be of interest to you Chip if you want the latest version of the DTA eprom - i just e-mailed Allan at DTA at about 3pm on a Friday afternoon a few months back and the new eprom was with me at 11am on the Saturday morning!
2 minutes to get the case apart and swap the eproms and jobs a good'un!
and it didnt cost me a penny
So might be worth doing that to get the very latest version?
