English Amiga Board - View Single Post - Installing A1200 ROMs

I've just got a pair of 3.1 ROMs for my 1200, with instructions tht say put the upper ROM in socket U6B and the lower in U6A.

Thing is, which ROM chip is which?
I have 391773-01 (28663A) and 391774-01 (29147A)

I assume 391773 is lower and 391774 is upper, can anyone confirm this?

Many thanks.
