I'm not very aware of that machine. However, I personally don't pay much
attention to ATARI as they are a machine not in my scope of interest. I
have to place limits on myself in some way :)

I tend to occasionally understate things. I did so in this case as there
would often be the person who stands up and says <their favorite bus> is #1
and then the list would degenerate into yet another pi--ing contest.
(Personally, I think VME is #1 indust. bus myself and fully agree with you,
but please don't tell anybody! ;) ;) ;)

Those PC104 systems are indeed nice for their small size.
