Ryan showed me this, had to laugh.
I don't remember ever having mine make music.

That's pretty neat. We still had a DM printer where I worked when I lost my job in 2009.   Thanks.                                                                  Roger.

That was pretty cool, Alan.  No I've never heard a DM make music but a lot of picture.

We had piles of them in the Lab for printing reports and I serviced them for years. From the Epson FX80 to much bigger and faster printers we had a lot of them. They were all replaced by lazer printers eventually. They are now serviced by ITservices. I don't touch any computer equipment these days.

I remember that Dot Matrix!

 

I remember my mom printing out stuff for college and that printing screeching.  Had the daisy wheel paper.

I've got one sitting on the desk next to me.  They're still the only game in town when you're printing 3-part forms.

Wow!  :worshippy1:  to the guy that did that :thumbs:  :thumbs: :thumbs:  

 

Way back in the day before PCs were invented, I worked in Data Processing as an operator and programmed.

 

We are talking the late 60s to early 80s.

 

Back them IBM had a line printer model 1403 which had a spinning chain with the letters on it, and 132 'hammers' that would 'fire' when the right letter was in the right place on the line that was being printed. Those hammers were fired by an electromagnet.

 

Somehow someone discovered that if you turned on an AM radio, and tuned it to the right frequency, it would pick up the noise generated by the electromagnets. Then they figured out that by having the printer print the proper characters that it would play music over the radio.

 

Just another of those weird tricks that Computer Folks have come up with over the years  :D :D
