Amiga motherboard (A3000) cleanup with Isopropyl alcohol: weird results

[rkauer]

 When my A2k fried, I discovered the Agnus was bust. And an associated TTL was busted, too. I was able to locate the problem thanks to the A500/2000 service manual (look at Aminet).

 Wonder if the 3000 don't have the very same associated IC (TTL 74HCT244 OR 74ALS244), it seats very near to Agnus. Major RAM problems comes from Agnus.
