Please excuse my ignorance, but what does the acronym BLT mean for that board?

A quick side-by-side comparison with the 1102 :
Bus and Ref buttons have moved to the Analyse menu
Has LAN interface, but remote front panel not yet implemented. PHY is SMC 8710A, so 100Mbit
Ridiculously long boot time - 55 secs v.21 on the 1102 - maybe still some debug code in there ? FW is V2.00
No WinCE license sticker on the back
Low-level noise performance identical.
Ref and FFT have dedicated size and position knobs, presumably to match the knob layout of the 1102. Not sire I like that these are on the left.
Still has external trig input on the back, but can no longer display it, which is as expected
The BLT board has gone to rev 3 but looks pretty much identical at first glance, apart from J104 now being fitted.
Might be interesting to swap into the 1102G...

I found an interesting article written by Daniel Bogdanoff about the making of an ASIC.  There is a picture of the same one you show in the article (revision 2 instead of 3) but it does not have the heat sinks on the chips.  In case you want to see them.

Thanks for a great read, Daniel!

Dave did a teardown of the DSOX1102G in March 2017.  You can see  in the chassis holes the future planning for the DSOX1204G.  Comparing Mikes pictures of the 1204 with the EEVblog teardown of the 1102,  the Main boards are labeled different.  DSOx1000AG vs DSOX1004AG.  It seems the 1004 board is a bit more complex.

Shouldn't be mission impossible to devise workarounds... ;)

The .ksx is a initrnamfs file which can be easily opened with 7zip decompressor.
