One in OP is Spanish, mbc is German... it would have a different model code for sure since it has a different language layout. May or may not have a different 092* or some other part number if it used a different protocol, depend on if custom order and how consistent Cherry was feeling then. In any case I am still 99% confident it is a G80.
Actually, the one in OP looks like it's Spanish-French, not Spanish. Groupe Bull is, no surprise here, a French company. Except during this era, it was actually owned by France. As in nationalized. Their primary markets were, no surprise here, France and French-speaking Belgium and Spain. (Nationalization occurred in 1982 and was subsequently re-privitised in 1994.)
The thing is, you're looking at a keyboard which is definitely Micral 30 era - 1985ish. But here's the thing: that's not a Micral 30 keyboard.
Notice, oh, I don't know, about thirty differences between the G80-0929 frame and the Micral 30? Give or take. And it's definitely not a Micral 60 keyboard, because the Micral 60 required a 101 key. It's not a Zenith because, well, come on. We know the Zenith keyboards from the era were Alps with an entirely different layout. And definitely not made by Cherry. It's not a Honeywell either. Might be a filler-part due to low stock on Micral 30's, but I cannot imagine why they would use what is probably a more expensive part. *headscratch*
