[GreenKeys] The Teletype Machine That Could Draw

[John Spigel]

I've posted a bunch, 125 or so, of additional TTY ART MP3 files on

https://5bits.net

Now just 170 shift, but will add 850 shift in next few days. I've 
rendered the ART in GIF format so you can get an idea of what you might 
be printing. I'll make up a fancier web display later.

I plan to collect a number of Christmas pics and add them as they become 
available.

I'm seekingr some files/ tapes that may exist that are from WX reports 
that used the weather service fonts. I'd like to create a couple of MP3 
files so we can museum demo. An M15 with the fonts would be a nice find, 
too.

73, John W1AN
