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"):

This looks to be made from an HP 64000 development
system. Like the one seen here:

I also believe the other is made from an HP 9825.
