I've read through all the SDM docs and grok them, and I got my friend's rig working so I can make the USB hardware easily. Have done some Basic programming in the past, so if you need some testing done, I'll be able to assist in that area and we'll have four TX-1 cameras to compare for glitches similarities, etc.
Two are US versions & two are "Japan Only" versions so we see if there are any differences.
I'm looking into making a 4-outlet USB trigger!
