I have to check the roms but the guy said it was the last version (v6 or 7 I think?). It was a bunch of stuff I got from a senior fellow who used to be a Amiga hobbyist with his son, got tons of stuff and he seems to know his stuff. Havn't check the HDD size but I am sure it's less the 525mb (Is a Quantum ProDrive LPS, came in only 3 sizes).
No corrosion that I know of and first thing I did when I got the amiga was remove the battery. Plus this didn't happen till after the upgrade.
All original disks, again from the guy. I tried the 1.3 disks that came with the A2000, 2.1 (original), and even 2.05 from an old A600. Same effect happens.
BTW, the A2091 was pulled from another A2000 I got from that guy, which died from corrosion. However this shouldn't effect the card right?
