The GMC-800 is being sold now in a fully new hardware version. It reports itself as GMC-800Re2.00, and is incompatible with previous versions of GeigerLog and RadPro!
GeigerLog has now been adapted; its latest version is available as a pre-release on GeigerLog's development site. Use pre08 or later:

The use of a new microchip raises hopes for getting fast performance. Well, the opposite was the case! For the first time ever I had in insert delays (!) at various stages of the GeigerLog code, just to accomododate this one counter. Imagine, even the old GQ clunkers GMC-300 were faster!
Adapting RadPro might take a bit longer; GQ has resorted to grinding off all labels on the chips, which does throw a few extra wrenches into anyone's attempts to create alternative firmware. 
And the much dreaded FET "feature" has been runied even further. The picture shows the outcome for a Poisson test for FET=5 in the top pic. This is supposed to look like the bottom pic, which is the History read out from the very same GMC-800Re2.00. The data are there; they are just ruined by GQ's infamous algorithm !
Draw your own conclusions.
