The Mini PET has been well received, but one thing appears to be unanimous, no one liked the keyboard. I think that was partly down to the blue switches TFW8b likes to use. The white soft touch ones I used originally were nicer to type on.
I have recreated the artwork as closely as I could based on the most common PET 2001 keyboards (I am told there are three variants one with different coloured number keys, and one with the light blue keys grey).
