If that's been popped during programming (there is an option in most programmers to do so, including my UniSite), then the PAL's fuse pattern is rendered completely unreadable. All it will do is function as programmed. How many do you have? If you don't mind mailing one or more to me, I'd be happy to try and read them, and store the map image (if readable -- see above) on a floppy for you, then send the chips and floppy back to you. FWIW, I've seen Data I/O 29 series programmers turn up fairly inexpensively (around the $100-$150 range) on the used market. I don't know where you're located, but if you can get hold of a 29B, with the LogicPak plug-in, you'd be able to read most of the PALs that were used in 'classic' equipment at least. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.
