At only 27MHz and 10 bits of data a CPLD is a viable solution. I've used the 9536 CPLD with good success, my logan project uses it (and connects it to a PIC): http://repatch.dyndns.org:8383/pic_stuff/logan TTYL -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
