Luke, I've been involved on this list for a year and half. That is quite 
clear and I wasn't implying that Joe was in charge of the spec.

What I was asking is for some additional details about the nature of the 
problem. Was it just an issue with the specific LCD, or with the way the 
RGB TTL lines labeled in the EOMA-68 spec. This is not clear from Joe's 
post.

If it was worked out off list (which is implied in another thread), so 
be it.

That's fine. Excuse me for taking an interest on an issue that is now 
clearly resolved.

Yes, I'd not caught up with the other thread when I posted. Moving on.
