So after a long hiatus, I have gotten back to some good ole 65x magic. Under suggestion of others I decided to make the leap to programmable logic. I have been using Xilinx ISE and its a bit different but it seems straight forward enough. I thought I would post this CPLD and tell me if im going in the right direction? will this work?

Just starting this CPLD 9500 series but what I have is the octal latch for the 65c816 to bring out the higher address lines from the data bus according to the datasheet, Its supposed to be equiv to 74x573 and 74x245.
Thanks

Welcome to the world of programmable logic dd!

I'd say you've chosen a perfect way to start too. Nice and simple. Now all you have to do is try it in a real world project. The 9536 is a nice choice and has speed ratings of 5ns. What voltages will you be working at?

I purchased some of the older 5v units. Although I hear the w65c816 will work down to 3.3v. I would prefer to keep the levels a little higher.

It is specified down to 1.8V, but it's not guaranteed to work above 2MHz at that voltage. At 3V it's guaranteed to work to at least 8MHz; and at 5V, 14MHz.
