The 8041 has the same pinout as the Intel 8741

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.
A Pro-Log M980 PROM Programmer with a PM 9054
personality module can read out the programs
inside.
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.
