I'm prototyping an LED display thingie and
was trying to find a
representation of how folks used to do letters on a 7-segment display.
The two historical examples I came up with were the KIM-1...
How were the displays driven? I.e., were the segments individually
driven (each segment under software control) or were they driven
by a "7 segment LED driver"? In the former case, you'd need a definitive source
for the
patterns used. (given that, I can build you a TTF or PS font)
I don't need a TTF or PS font (I'm doing a bit-mapped emulation and I
already have the code done to render all possible patterns on some
simulated 7-segment displays), what I need is the definitive source
for the patterns.
