True. But if you've ever had to do anything with thickwire (other
than just look at it!) then you'd never confuse it with an AUI
cable :-) That said, AUI cables come in at least two girths, one
for the longer lengths and a thinner one (about thinwire diameter
and much easier to work with) for those shorter lengths (1,3,5m??)
typically used within a single rack. All the thicker AUI cables
I remember working with were blue, all the thinner ones were a
cream colour (slightly lighter than the typical thinwire colour).

The simple distiction, of course, is that an AUI cable is the only
one you might mistakenly try to use as a VGA cable :-)
