Received MPG3204AT -EU which does re-cal and reads modules.
but 3D and Rom not read.

Check flashRom on pcb and discover the board is not native.
The 3204 is x82-80C2 and the pcb is from 3102AT with xA9-80B5,
but reads SA fine with no clicking. 2Bh is 01.

Anyway, took Rom from matching 3204, cleared adaptives,
made 2Bh as 01 and wrote to disk in standard mode - voila !
All data retrieved perfectly.

So I have some other 3204 with native board mising, but this
3102 pcb just produces clicking on them all. I conclude that
this 3204 has no adaptives.
