The fat agnus from the a500 is only a one meg chip. Wouldn't work even if you pulled the zip ram, and would result (I imagine) in a green screen.

Hey T3000, are they not pin-compatible? I believe I had a 8273B work in an A500 rev. 6a, although I don't remember it so well, so perhaps I'm only dreaming.

I also see the poster of this thread confirm that a 8372A works in his A3000:

Could you verify if it would work? Thanks

Yes.

hmm...   I looked and looked, but could not find anything on the 8273B.  Must be some kinda super secret "military spec" chip.  Either that, or you transposed some digits...  :-D

LOL :-)
Yeah, I looked very hard as well and couldn't find anything, except your post and the one in the link.

Looks like from the other topic, that the 8372A one meg chip may function in the A3000. I'm not gonna start chip swapping to find out though...

Soooo many variables...

Yeah, so he says in that link... but I'm not so sure as I haven't asked him (yet) to verify this for me, and also the statement isn't so clear.

I also asked the resident Agnus-gnostic master himself, AlexH and he says emphatically: NO


@ALL:
What Doobrey says about the possibility of a red screen caused by something other than a faulty KS is right, and the same goes for pretty much all the other colors: they aren't *necessarily* caused by an actual *chip* itself failing, but also possibly from a faulty connection/wiring to said chip(s), or a combination of faulty chips and wirings (as in my sad A3000 case...).

@57goldtop:

Can you verify if a 8372A worked in your A3000? (as mentioned in your thread: http://www.amiga.org/forums/showthread.php?t=30076)

As for the part #s, yeah, it makes sense.

I saw the http://www.jochi.de/speichertabelle.html site from the recent newgroup threads, but I'll wait for AlexH's all-encompassing (and Englishized) Agnus Encyclopaedia! :-)
