CommentManual for Janome New Home 580 and 581 sewing machines comment by juneHits | Last Modified 2015-11-12 Hi, I also have a Janome 180 but it looks different from yours. Where yours is dark on the front mine is red so I had to look twice, but I think all the knobs and buttons are the same. I downloaded the manual some years ago but I was hoping to get the real thing. Wishful thinking probably. xx
CommentManual for Janome New Home 580 and 581 sewing machines comment by Elena EmblenHits | Last Modified 2016-09-20 Hi, my 580 looks exactly the same as yours, but it is different from the manual. Where 581 has built-in stitch patterns and a button hole dial, my 580 has pattern cams. So this must be the difference.
I haven't seen another blue one anywhere, they appear to be mostly all beige and with a differently looking stitch width selector, although otherwise the same - with cams.
Do you know what year your machine is from? I was told 1959, but I'm not so sure.
