David,

My old EPIC programmer served me well, but whenever I made any change in WindowsXP I started having programming problems. The guys here help me narrow it down to Windows poor driver/memory management. No one uses printer ports anymore I guess. I upgraded to the MeLabs USB programmer, and it works great. If your EPIC was the same as mine you could try two 9 volt batteries instead of the transformer. Have you looked under the View menu at the memory to see if it changes after you program a chip? It should look like the hex file that you attached earlier. You might also try downloading the Beta loader software from MeLabs website, it should work with your EPIC programmer, and if you haven't already, take a look at http://www.melabs.com/support/epicfixs.htm

Of course I might be leading you astray, but Darrel or Steve or one of the other gurus will figure it out. I don't mind being wrong, I still learn something!

Merry Christmas to all!

Jerry.
