Stumper: What computers are these?

[Seth Morabito]

Alright, I admit it.  I'm stumped.

BBC has a series, "Look Around You", a comedy program based on late  
1970s and early 1980s educational programming.  Season two included  
an episode called "Computers", and featured these two fake "home  
computers".

The Bournemouth ("The most powerful computer in Britain"):

The Petticoat 5 ("The first computer designed just for women"):

I assume that these are genuine British classic computers that the  
producers painted and re-badged for television.  But what are they?
