This is the new "local bus". It doesn't have anything to do
with ISA or EISA. VESA is a video standards organization.
Whether or not a machine has local bus it will also come 
with EISA or ISA (or MC).

Depends. I'd say most of the posters here would say get a clone,
but I realize there is another side to it. If you do get a clone
do your research well. A dealer who will be around a long time 
would be good, quality components are imperative. The video card
in particular is very important if you plan on using Windows and 
OS/2. The same machine can drag or fly depending on the video 
card you put in it. The posting you responded to has to do with
clone research. The original poster was wanting to know about 
clone parts, i.e. whats good or bad. You should also do the same.

No its hard drives only. Two drives per IDE "paddle card". The
controller actually lives on the physical hard drive, which ac-
tually use some advanced form of RLL encoding. Fast and cheap.
