Apple II emulator for mac - need diagnostics

[Kevin Lund <kevin@cassandra.ucr.edu>]

Hi, after waiting years for a decent apple II emulator for
the mac, I broke down and wrote one.  It works pretty well,
I guess, but I'm having a problem running prodos.  It gets
alomst through with the boot, but hangs up when it clears 
the screen (after the title page).  This is prodos 1.0, by
the way (I've been out of it for a while...).

Now, the processor emulation seems ok; it runs everything
else I've fed it (except Wizardry, it has some *&^%$ protection
I haven't worked out), so I suspect my ram card emulation.
It works fine for loading basics up under dos 3.3, but that
doesn't exactly give it a workout...

So, to get to a point, does anybody have some sort of diagnostic
that will exercise a language card?  Alternately, anybody
know prodos inside-out and want to have a peek?  This is really
chapping my hide...

  Thanks,
