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. Rolf
