I've already reworked my PCB to take either of the Sparkfun products.
Since
their serial interfaced parts won't be available until late March, I've
ordered one of
their 1" 128x128 OLEDS to play with. I think it was you who mentioned
this
here
some time ago. It is better than the Osram part in that it has some
built-in high level
graphics command that greatly simplifies life. Their serial products have
similar
commands so the switch should be easy.

That is a bit disappointing to hear, but since I originally wanted just
yellow, I guess it
shouldn't be a problem.

Thanks for the links. If this ever evolves to something I want to show
around I'll
probably have to use a bigger display. Sparkfun have a very expensive
($160)
2.2" QVGA display that I think is plug compatible with their 1.7" ($100)
OLED but
it might still be a bit small..

If text was all I wanted to display, I would have gone that route. As it
is, the
high level commands in the Sparkfun displays eliminate any need for a
buffer.
