I've got one here in my II. I can honestly say that it pretty
much works. The display is VERY slow ( they say that it will be
improved a lot in a month or two with the next release ) and they
darned thing will hang up on some occasions, but it mostly works.
I wish the I/O was a little more flexible and you didn't have to
write a big file out there to act as your DOS filesystem but...

One of the nicest things you can do is write a DOS file to the
Mac 'device' ( the Mac filesystem ) as drive D. The 'normal'
filesystem is drive C ( its a big file to the Mac OS ). This lets
you get right at DOS type files that you might have imported via
the DOS floppy. Also, you have to hook up only ( currently ) the
one type of floppy at a time.... would like to have scsi on the
DOS board VERY much....

Haven't done any real benchmarking but it seems to be at about AT
speed EXCEPT for the display speed which is really slow ( SLOW )

I'm waiting to see how well the software-only DOS emulation works
when it is really available.
