RE: the discussion on converting the Sun Remarketing Mac XL back to a Lisa
2 - I called Sun Remarketing and spoke with their most knowledgable Lisa
person (thanks Marion!) who was less than encouraging about the project.
According to him, it is not just replacing a few ROMs and PALs, and removing
a transformer from the CRT yoke - it requires replacing the main logic board
from an original Lisa, and unless you have a wrecked Lisa, that item may be
a little hard to find.
I thought the only difference between the logic boards was the
PROMs/PALs. Of course, not owning a Lisa, I can't be sure about this,
alas...

This is what I've heard, too. In fact, one of the newer Lisa gizmos sold by Dafax is a
"ROM switcher" so you can use both the original Lisa H-roms and the modification
3A-roms without further tinkering. (I guess you'd just put up with oval circles and
whatnot in Mac apps, since the ROM switcher doesn't do squat about changing the
video.) All these repair manuals say "hang onto your old ROMS so you can run Lisa
stuff in the future" which seems to indicate that it's feasible to revert the
change. ???
