hello Wilko,
thanks for the tip. Changing the manufacturer's name did not solve the issue (none of the 7 available worked), yet removing the "check ID" option did result in the programer reading the content.
So, back to square 1, looking for a better explanation for this scope failure.
have a good one

Did you select the correct vendor & partnumber? EPROMs can be identified by a programmer using their electronic ID. The programmer can make use of that info to optimise (= speed up) programming for example. An ID check error in my experience
smells like the wrong part/vendor has been selected in the programmer software.
