	Yes and no. Like Turbo, Lightspeed Pascal compiles (and how!)
programs, but you can't run them. The problem here is the same one that
kills MacWrite -- specifically, the two-byte difference in exception stack
frame size between the 68K and the 68020.

	THINK has produced an intermediate version called 1.01, which
was a fix designed to work with third-party 68020 upgrades like
Novy's and the Levco Prodigy series. It works fine on those, and
works fine on the Mac II. The problem is, there are some incompatibilities
between Lightspeed Pascal and System 4.1 and the new ROMs (SE and Mac II).
This isn't because THINK broke any rules; it's because the implementation
of ClearMenuBar() changed, and som important handled data gets trashed,
etc, etc. The result is that highlighted text (menu titles/items, buttons)
are completely blacked out. There are also a number of interesting
graphical effects, but nothing fatal.

If you just got a Mac II and you're having problems with LSP, call THINK
and they'll help you out.

The next release (due Real Soon Now) wil fix all of these problems;
the company's working *real hard* on this.

Oh yeah -- I'm beta-testing this stuff, but I have no
other affiliation with THINK Technologies, other than
as a happy user of their products.
