The first refurb I attempted was the ZX Spectrum 48K rubber keyboard model.
It arrived in a very bad state.
Its an Issue 3B board!
I completed the Composite Video modification that allows the speccy to work with an RCA composite cable on a new TV

The metal keyboard plate is very bendy and once it has been removed, it is difficult to flatten it out proplerly, so I just left it as is. The printing on the rubber keyboard is also rubbing off due to excessive use during its life.
The redeeming feature of this speccy is the genuine PSU with the inline reset switch.
