Help with identifying monitor - might be fixed frequency?

Hi. I was hoping perhaps someone here could help me. I recently was given
a nice 20 inch monitor by a guy who was going to a flatscreen, and didn't
have space in his apartment for the older monitor. He was running it on a
mac, with an adapter which had dip switches. From what I've found out, I
think this is so you can run an IBM monitor on a mac (not sure). The cable
ended in RGB and the black sync wire.

After a little digging, I was able to buy a vga cord that had the four
outputs. However, I tried to connect it, and the monitor looks all
scrambled. I checked the inputs, and they're all set.

My computer is a P3-500, running with a Voodoo3-3000 card. There are no
distinguishing marks on the monitor to tell me who makes it, or what model #
it is. There's a serial #, 1894470020, with a small DM subscript
underneath, on the back. Digital Machines? The controls on the bottom of
the monitor are v-stat,h-stat,v-cent, brightness,contrast, power.

I'm hoping to find out what make/model this monitor is, and what the
refresh,resolution, and such should be. There's a utility where I can
change the refresh of my video card. It might only work for windows, but
that's all I work in anyway...I can stand it garbling until windows boots.
If I have to, I'll see about getting a Gemini card, but I'd rather not if I
can avoid it.

I've included links to some quick pictures I took of the monitor, as well as
the adapter for the mac, in case that'd jog anyone memory. Thanks for your
help in advance.

IIRC MACs use Sync on Green (SoG) which means the Sync Signal is
combined with the Green Signal. If I *do* remember correctly, then this
also means that your lead with a sync on the black wire won't work. You
could try some of the 65,536 combinations of those DIP switches.... you
might be lucky and get the one the re-routes the sync back on to the
black lead.
