Nsc800 or Z80- a win32 cross-assembler

I would like to know if anyone else knows of an inexpensive (less than $400) Nsc800 or Z80 win32 Cross assembler. I've looked at simtel and there's are all DOS based ones. 2500AD and Avocet are not possible candidates because they cost too much. All I need are a URL(S) of a company that fits my need...

Re: Components Equivalents

yes, motorola is freescale.
it is also at Onsemi main page.
in the middle of the page they have a cross-ref box. eneter your request here, and click the submit button (i think). this works for non mcu parts as freescale does those.
hope this helps.

Some dtatheets may be corrupted in transmission over the internet, and you may lose some graphic and/or titles to figures and such. a recent file i downloaded had just such a problem, and i had to go to www. onsemi.com t...
