I can only guess he means an LC PDS 601.A PowerBook 500 upgrade card?!?!I have one of these in my Mystic Colour Classic
I have a 50mhz 601 in my Q700, but I also have a 100mhz that I have been too lazy to put in it. Those 601 cards make a huge difference and some people have even gotten Mac OS 8.5/8.6 to work with them. I would guess that it would be possible to get 9 to work, but I haven't found any documentation anywhere of anyone who's done it.
