Here’s a video - a minute or so in you’ll see a number of Mac Classics and then a number of S-100 machines (including the Vector 1 as seen on John Monahan’s S100 site)

Here’s a Flickr album, cued up at a table of Ultratec communications devices (possibly telephony for the Deaf?) You’ll also see a Lisa, several iBooks, a fully loaded Mac II:
Edit: the BBC Buggy chap is Steve Crozier, more turtles, micros, and info on his website
