Yes, it is possible. I have used AMD and Intel 27C400's, although it is possible to use a pair of 27C200's for machines that require 2 Kickstart chips (IE 1200/3000/4000).
By the time you find a programmer, eraser, blank eproms, and learn how to split and or byte swap the files to get them to work correctly it's usually just easier to buy them. Not to mention the legal aspect.
Let us know what your desired end result is, perhaps we can help. Is it a custom project?
