Agnus (2 MB) 8375 R0 318069-18 A500+ (PAL), A600 (PAL)

There is definately Agnus chips silked 8375R0, but the only picture I've been able to find is of the 390544-01

As both these chips are designated PAL I think there has been a mixup, but more information is required to be 100% sure.

A date code of 0392 = 1992 is not consistant. There are earlier versions of the 390544-01 8375 WITHOUT the R0 dated 3591, 4291, 4391, 5291 = 1991. Need some more pictures of R0's to be sure!

Hmm, I would assume that they introduced the R0 silk on later chips because they ran two lines? There are some 8375 318069-10 dated 0992 which is only 6 weeks different.

Can ANYONE provide a shot of a 318069-18? To be doubly sure?

P.S. Does anyone know how to work out the month from the Commodore date codes?
