Research Machines - LINK 480Z
In good clean physical condition. It has been tested by plugging it in and the fan works and the keyboard light comes on but the picture on my LCD telly is terrible.
The picture is rolling on the screen very quickly so I can't really make out what is going on!
However, there is text and when I hit certain keys the text changes significantly, so I *think* it is working and just incompatible with my new LCD telly perhaps. I have read lots of times that machines like ZX80's etc only really work on older tellys.
I can't promise that this machine is fully working but my basic tests are kinda promising.
There are yellow school security markings on the right hand side but I reckon these could be removed with a little elbow grease.
