Microprossesors/Demo Boards which program in assembly

[bill haygood]

Hello, I am proficient in assembly language of the Free-scale line of microprocessors and I would like to learn other brands. Can anyone please tell me if there are any other brands of microprocessors, demo-boards, or IDEs that allow programming in assembly? If you know of a specific hyperlink please give me that too. I would like to try developing with assembly with another brand. Thank you.

Here's a list of processors http://en.wikipedia.org/wiki/List_of_microprocessors
I would expect at least some of them to have links to evaluation boards and development tools.
