I deliberately omitted the Lisa, Lisa 2, Lisa 2/5,
Lisa 2/10, and Macintosh
XL because they do have a ROM-based debugger. I've used it a lot lately.

Actually very much by choice.
Is it more or less useful than the one in the
Macintosh?
Less. It lets you examine and modify memory, and jump. That's about it.

2. It is not clear that FORTH can be considered a
debugger/monitor, any
more than BASIC can.

hmm... FORTH gives you low-level access to memory; you
could write all the
features of "real" debugging monitors if they weren't already there (e.g.,
hex dumps). I guess the potential is there, and it's there with FORTH a lot
more than with BASIC.
FORTH is not really much more usable as a debug monitor than a typical
8-bit-microcomputer BASIC.
Both let you examine and modify memory in a crude fashion. You can write
programs in either to make this more convenient. Both let you start execution
of machine code at an address. But how do you single-step through the
machine code using either?
