There, problem fixed! 030 upgrade! I crossed my fingers that my HMMU socket was not specific. I really expected it to be since my board revision is one of the firsts. But I guess for once when Apple said "a limited number of machines were affected by...", they actually meant it! lol

So once I was good there, I pulled the 020 and put in the Daystar Mac II adapter with 030 upgrade card. It amazes me that old stuff like this that has been removed, stored then reinstalled still works.

Fun stuff!

So I think I will just leave this RAM in there. I am certain that this 20MB kit was originally for the Mac II and bought as a whole. That would explain why the cards for bank A only have 1MB each, the max Bank A can take no matter what apparently.
