Or you could just create your own official "COMMODORE 64" graphic using Illustrator and add it yourself
I drew the 'Commodore 64' badge from the original computer as a vector, in illustrator, some time back, so I just used the text from that,
but unfortunately it doesn't have the 'K' and I can't be arsed to make an attempt to replicate something as a guess, besides this is how
it should really look, never mind the fancy fonts
Anyway, the boing ball belongs to the Amiga and not the C64, so why do you want to spoil that awesome image with text?
