Well, it's leaps and bounds better than composite, but nowhere close to RGB. I can use the machine in hires, but hires laced is still pretty bad and almost unusable (if you want to keep your sanity).
Now, this is also on an LCD screen... I haven't tried it on a tube TV or monitor yet... when I do I will post the results.
I'm really beginning to think that a 1084s is the most practical monitor for these computers...
EDIT:
The clock came with my 1200 (used). Not sure where it was purchased... I was surprised to find it there when I opened it for the first time because I'd never seen one like that before.
