Hi cctalkers,
A while back there was a URL posted somewhere on this list about a
(1950s?) character generator which worked solely by mixing harmonics,
with X-Y output to connect to a display tube. It could only generate
the digits 0-9, but was a seriously impressive piece of kit
nonetheless.
I recently wanted to show this to a friend, and couldn't find it with
any amount of Googling.
If someone can remember this site, or has it bookmarked, I'd be
endlessly grateful for the URL.
Thanks,
Ed.
