I do hope that's not a professional modification!
I can imagine the sales man giving it the smooth spiel - "Yeah, we make VIC-20's for schools, specially modified - juuuuust sign here on the dotted line for your order...we only ask for double the listing price"
And when the purchasing decision is done, he yells out back 'VERN, BREAK OUT THE SOLDERING IRON!' followed by the sound of banjo music and 'yeeeeee-haaaaaawww!!'
