Actually, I had the trace cut and the wire to the rom, but I also had an AdRam card in it too. I couldn't get ANY kind of accelerator working with it.
That sucked, 'cos I was given an A2000 with a rev6 mobo that didn't like any accelerator either. I spent 200$ on an Apollo 030/50 back in 1997 and NEVER got it to work. Eventually, it was destroyed, along with my A3000 and a bunch of other Amiga items by my ex lady. Well, I wouldn't call her a lady. A friend with benefits was more like it. Then again, she wasn't really even a friend.
:-( Sigh....I really miss my A3000.
