Nor can the z-80 or any other 8 bit micro I've seen. Commodore chooses the 6502 mainly because they designed it, or rather Chuck Peddle, designer of the first PET, designed it. But he did a good job if you remember he wanted a fast, optimized 8-bit processor. It's been proven time and time again that when coded properly, z-80 programs that do the same thing are twice as big and several times slower than 6502 programs. -- Brad Templeton, Looking Glass Software Ltd. - Waterloo, Ontario 519/884-7473
