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 latter case, you can lookup
the display pattern created by that driver chip and emulate it.
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)
