'Antique' computer purchase

I love buying stuff like this. I'm pretty sure it is rare because this is the only web page I could find with any information about it :

Mine is boxed but without instructions - a steal at £5 (?)

Probably not so much because it's rare, more because there where soooooo many of these style of consoles around (100's of clones after the first few). Still if it's boxed (shame about instructions tho), and working it's probably worth the fiver.

It looks nice :D
How does it play?
