iPod design more retro than we thought?

Would of been cool if the Lisa was the first Apple computer to play music (given that the mascot is holding an iPod), so I thought I’d take a look at the 22 year old Apple Lisa User Manual (downloadable as a PDF) to find out! Didn’t find a mention of music (though could of missed it) but something that nearly made me fall off my seat, before I realised what it was, is the following pic, taken from page 226 of the manual…

The first pic is the bottom of the Apple Lisa mouse!
