Liam,
i'm sorry, but Chuck is right.
Your link directs to a photo showing a terminal.
The Topper was put into market as a intelligent terminal for
stand alone use as a CP/M machine and for remote issues as a
IBM compatible terminal.
In fact the Topper has a 8085 CPU for the terminal part and a Z80
for the CP/M part.
On booting the system disk you should be asked which functionalilty
you want.
There is a marketing brochure i have found in the www, where the
Topper is mentioned beside some other Beehive terminals.
