bearpawz, Try an Allegro 6832. Attached is the data sheet...

If only they had that in DIP package for bread-boarding. I like to prototype my circuits on breadboard before going through the hastle of making a pcb. In fact, Ive got a few 6818's that are in plcc package, even have the plcc socket but its a quad socket and not dual so still hard to protype with out some sort of adapter.

Not sure it'll work with the Allegro chip though>

bearpawz, Actually they did in the past. I have some of them and wanted to get some more but sometime yearly 06 they stopped making the 40 pin dip package. Darrel has a great idea. It could also be usefull for some of those plcc44 pic's as well.....

The max7219 can easily drive 64 leds. Not quite all that you need though. They come in dip packages and are pretty easy to interface too.
