no disputing that.  Glad Tony made his point, I was curious if it was 
early enough to not have had what we are accustomed to now days.

Previous owner had it in an S100 system?  that is my remaining concern.  
I have some pretty convincing boards which look like but aren't ducks.

Interesting card, thanks for posting it.   It'll be interesting to see 
what you find.  I'm also interested in what the referenced info source, 
from Bill Degan, turns up.
