According to the schematics here, it is the 8372B / 8372AB part.

So if these schematics still apply, the correct part is 318069-03 / 318069-039.

This is a quote from A1K.org

I have contacted via George Brown. He confirmed that AGNUS 318069-11 (2MB NTSC) and 28.37516 MHz oscillator function in GBA1000 Rev.4!

did i mention i am ordering a few of each :)

Nice, these are much easier to obtain :thumbsup:
So I take it those schematics are of an earlier revision (there's indeed a suspicious _01 suffix), are the rev4 schematics available somewhere too?

is there stock of 318069-11 somewhere?? going to be hard to find the right agnii if someone does not find a box of a 130plus of these babies :(

so is that the same for pal as i read thats ntsc doesnt mention pal on that agnus chip?? so i take it we need the pal version?

This is going to take about a week to set up so be patient.

I think there will be a lot of us that aren't used to ordering these types of components. If the more experienced parts purchases in this thread (Kipper, PJM, BLTCON0, etc.) can put together a group-buy of the hard-to-get bits, or even a complete set of bits, count me in.

Count me also in or group buy of parts like cpu ram etc.
I already obtained a Amber and Video hybrid but sure can use the other hard to get parts.

I just bought 25 of the NTSC -11 Agnus and 28.375 MHz clocks. (I have the schematics for the rev 4 as well as the board design). There are lots of the Agnus -11s available. I cant buy too much as it is sucking up all my cash

I'll ask the person who i got them from if he wants to do individual orders. I bought them for people who want to do the group buy. price will be about 7euros each (i paid 6 plus shipping + i'll prob get nailed by customs for some duty or other

(I am yakumo9275, I dont remember why I have a different nic on amibay than eab + amiga.org).. as an fyi..

This video could be very helpful for people not too sure about how to solder chips on their boards.
