Yes. My first suggestion is to try getting it going on the 7200
first. In my experience, that's a less tricky task. Once it works with
the 7200, then you know that most of the equipment works, and it's just a
matter of getting the right settings for the IIsi.
The trick with the IIsi is that it's sync-on-green. The built-in
video on those machines is also a little less tolerant of what monitor it
wants to be talking to, in my experience. So, I would start with the 7200
(which knows what VGA is and should work with just a straight-through
adapter), trying to make it work at [EMAIL PROTECTED] with the switches on the
adapter. Then, once that works, change sync mode to sync-on-green and
give it a try with the IIsi.
Incidentally, this all goes out the window if you're using an
add-on video card in the IIsi. Then, without knowing what sort of card it
is, it's anybody's guess what it will and won't work with.
