HC logic with 6502+rigging up a crystal

[Rob Thomson <rob.thomson@vuw.ac.nz>]

Hi,

Can I use a NMOS 6502 or 6522 happily with 74HC CMOS logic?

Also, what is the best way to get from up a 4Mhz crystal to two
opposite 1Mhz signals. eg. what capacitors, resistors and logic
(latches or counters?) would I need to do this and how.
Is it easier to get a 1Mhz crystal and invert it somehow (how?)
to get these two opposite 1Mhz signals.
These signals would be going straight to a 6502 and 6522.

Thanks for any help,

Rob.
