Hi,
Bought two other oldies yesterday, with dead HDs unfortunately .
That is a Powerbook 180c, and a 170. The two are booting alright on floppy or zip.
The 170 attracted my eyes cause it as a video expansion card for external screen :

here a pict of the card:

It's apparently the same as here :

other than that , pretty standard:

The 180c had a loose screen bezel cause of broken screw placements, it's in the repair shop now :


Otherwise boots ok on floppy:

It also had two strangely placed expansions cards ,one above the other, but not well fitting , i suppose one is RAM, but what is the other ? Could you help me identify these ? :
