U213 GAL chip on Amiga 4000

[8bitbubsy]

When you upgrade an A4000 from Super Buster 9 to Super Buster 11, you also need to upgrade U213 (GAL chip) from 391477-01 to 391477-02 to prevent a potential Zorro<->chip RAM access problem...
My Amiga 4000 motherboard does not have the version sticker on U213 anymore so I don't know if it's a -01 or -02. Is there any way to find out by poking some hardware addresses or so..? I assume not, but I want to know just in case.

Also, is the JED file for 391477-02 available somewhere? http://www.amigawiki.org/lib/exe/fet...a4000_u213.rar seems to be 391477-01 ...
EDIT: Wait, it seems to say 391477-02 in the filename in the .RAR from that URL, but 391477-01 in the info on the site.
I've ordered a couple of new GAL16V8D-10LJ now, I'll program it when I get it.

that's good to know - I've just purchased a buster 11, but didn't know about the GAL..

let's hope that file really is a "-02" ;-)

Has anyone confirmed if the file is U213 GAL chip 391477-02 ?

I have a Buster 9 and will upgrade to 11 but need this chip? Where to source?

This tester can likely decode the GALs -- https://www.ukvac.com/forum/threads/...teroids.60738/

Wait, what?
I seem to have missed this missive entirely. Can someone point to where this is documented? (Because I have a Buster 11 and a -01 label on that chip. It was upgraded while C= was still alive by their official national repair firm.)
(In case anyone is asking; I can't confirm that -01 works just fine with 11 - my 4000 has been temperamental(I suspect literally so) and has gone from Not Ideal to So Many Wrong Things.)
