HP40GS vs HP50G

The 4 calcs, 39, 40, 48 and 50 (ARM based) have virtually the same HW.
The differences lies in the screen size and (but I am not 100% sure) the Ram size.

What I do not remember is if there is a detection mechanism to let the SW detect which of the 4 HW it is running on.

If this is the case, flashing the code from one onto the other will not work.

I vaguely remember Saturn assembler pseudo-opcodes like ISBIGAPPLE? or something like that, used to detect different hardware versions/screen sizes. It could at least detect between 49G+ and regular 49G (large vs small screen).
I don't know if the 39 series had something similar.
