You might be surprised about who sometimes reads this thread and does have that information. I'll take a look for sure, if it appears here.

My best guess (which doesn't work) is that it (the first update) is called "8R29-14C026-AB" (-AA will never have been made available).

For an FG2, it's not "BR29" like most of the stuff in one, because some of the electronics came from the SZ which seems to have come out first, and which is "AR79".
