As a side note, does anyone have a schematic of the ROM adapter? If the ROM gets released I might burn it to some real ROMs and throw it in my retail Mac 128 for a laugh
It isn't necessary to have the adapter. You can merge the contents into a Hi and Lo ROM as used on the production Macintosh board. Some people have already done it a few years ago with the newer Twiggy ROM version.

I wonder if the PALs have the security fuses blown.
I'm guessing as it is a prototype and still very much a development system there is a minor chance that they would still be readable by a programmer.
If so, that's probably the only way to get at least some of the PAL equations for the macintosh!
