Great!
I've sent some files to actinium to get some additional data points as he seems to have an earlier firmware version. If something works for him that is not working for us, it might be helpful in finding out why.
I've been shooting twinned TX-1's by "double-thumbing." While it works pretty well for a lot of shots, I'm really looking forward to being able to use a remote trigger and all the tools in SDM!
Thanks to everyone who's pitching in here and special thanks to ewavr for his help and to David for all his hard work on this. Together we should be able to solve the keyboard problem and get this camera ported.
