Yes, Graham, those are the 'real thing', National Semiconductor DM prefix parts as originally used in the MK14 and widely supported by historic high end programmers, including mine.

If you PM me, I'll be happy to program them for you and even test them in a real MK14 before returning them. All I'd need from you would be a stamped, addressed return jiffy bag.
