It's the same pinout, but the 8041 is NOT rated for application of
+25V to the EA pin, as used to do ROM verification of the 8741.

Does the Pro-Log have a specific setting for 8041, or are you using
the 8741 setting and overstressing the part?

I've successfully read 8048 parts using a programmer configured for
8748, but I only did that on parts that I could afford to sacrifice. I
don't have spares of the IOC 8041A, so I'm building a kludge to read
it properly without applying 25V to EA.
