If you are not committed to using those, you can buy similar LED matrix
displays from Avago. (I believe [not sure] they bought the [old] product
line from HP.)

They have some models with a serial interface, which is much easier to
interface than a conventional matrix.(And your pick of two different reds,
orange, green or yellow):

"The HCMS-29xx series are high performance,
easy to use dot matrix displays driven by
on-board CMOS ICs.
Each display can be directly interfaced with
a microprocessor, thus eliminating the need
for cumbersome interface components. The
serial IC interface allows higher character
count information displays with a minimum
of data lines."
