When the IC's didn't found at data bank's defenetly...maybe analog IC or broken logic or analog.

Sorry - your point is what, exactly?

Very nice for third countries but...            01/01/70 00:00      
   My Advice            01/01/70 00:00      
   Today's top award for Stating The Blindingly Obvious...            01/01/70 00:00      
   Doesn't make sense            01/01/70 00:00      
      A microcontroller is a nice logic-chip tester            01/01/70 00:00      
         device in question is not for identifying unknown chips            01/01/70 00:00      
            Wasn't talking about linked device            01/01/70 00:00      
         IC logic still popular here(used)            01/01/70 00:00      
            sure, but            01/01/70 00:00      
               sure, but, but            01/01/70 00:00      
                  sure, but, but, but            01/01/70 00:00      
            Limitations            01/01/70 00:00      
               Areas of Doubt and Uncertainty            01/01/70 00:00      
                  I can imagine one case            01/01/70 00:00      
                     That would have different pinout            01/01/70 00:00      
                     what is all this about identifying chips            01/01/70 00:00      
                        See Richard's post            01/01/70 00:00      
                  Brute Force - The IC pins would curl up before finish            01/01/70 00:00      
                     Actually not too ahrd/expensive to detect chips            01/01/70 00:00      
                        But            01/01/70 00:00      
                           Of course            01/01/70 00:00      
                              Again, it depends on your goals            01/01/70 00:00      
                                 Scope of project is important            01/01/70 00:00      
   It's more interesting            01/01/70 00:00      
   both of my old portable programmers do this            01/01/70 00:00      
      Is there codes?            01/01/70 00:00      
         What, exactly, are you looking for?            01/01/70 00:00      
            unknown is hard....known is easy?            01/01/70 00:00      
               it's possible, but not reliable to check for unknowns            01/01/70 00:00      
                  xeltex superpro            01/01/70 00:00      
                     be careful ... that was several revisions ago ...            01/01/70 00:00      
               RE: known IC logic for test is easy?            01/01/70 00:00      
                  unknown....            01/01/70 00:00      
                     Pardon??            01/01/70 00:00      
                     IF you can't recognize the part, THEN discard it!            01/01/70 00:00      
                     The most likely reason you'd want to do that ...            01/01/70 00:00      
         The code was compiled and in a library            01/01/70 00:00      
            Place..The code was compiled and in a library            01/01/70 00:00      
               Will that help?            01/01/70 00:00      
                  in the future...            01/01/70 00:00      
                     It's just a small-C compiler with intrinsics for SuperPro            01/01/70 00:00      
                        help??            01/01/70 00:00      
                           Can't you just go from first principles?            01/01/70 00:00      
                           If you want that software, you should contact XELTEK            01/01/70 00:00      
                               The code was compiled and in a library???            01/01/70 00:00      
                                 Well, obvisouly!            01/01/70 00:00      
                                 The hardware for this sort of thing is not rocket science            01/01/70 00:00      
                                    library binary            01/01/70 00:00      
                                       I can't purchase the expensive SuperPro            01/01/70 00:00      
                                          homemade            01/01/70 00:00      
                                             this makes no sense            01/01/70 00:00      
                                                missing??            01/01/70 00:00      
                                                   no, I am not            01/01/70 00:00      
                                                      not so fast ...            01/01/70 00:00      
                                                         while all that is valid - to an extent            01/01/70 00:00      
                                                            kitchen table...            01/01/70 00:00      
                                                               Kitchen-table = home built with lacking tools/knowledge            01/01/70 00:00      
                                                                  understand....            01/01/70 00:00      
                                                         Can often be solder problems            01/01/70 00:00      
                                                      multiply            01/01/70 00:00      
                                                         if you use that many ....            01/01/70 00:00      
                                                            work's            01/01/70 00:00      
                                                               because            01/01/70 00:00      
                                                                  You're right in large part, but ...            01/01/70 00:00      
                                                                     did NOT bring this up for any other reason            01/01/70 00:00      
                                                                  back...            01/01/70 00:00      
                                                                     Can have uC or PC as master - just different advantages            01/01/70 00:00      
                                                                        You'll need lots of storage.            01/01/70 00:00      
                                                                           For what?            01/01/70 00:00      
                                                                              You need storage for the 250K test vector sets            01/01/70 00:00      
                                                                     Yes, you have to do the work            01/01/70 00:00      
                                                               "works (sic) flawlessly (sic)"            01/01/70 00:00      
                                                               You haven't the means to determine that it works flawlessly            01/01/70 00:00      
                                                                  XOR normally easier than trying high-end drive + sampling            01/01/70 00:00      
                                                                     That does work if you have one functional part for "seed"            01/01/70 00:00      
                                                                        Can perform time calibrations without specific seed            01/01/70 00:00      
                                                                           None of this works with just an XOR            01/01/70 00:00      
                                                                              Just an XOR?            01/01/70 00:00      
                                                                           These assertions look entirely wrong to me.            01/01/70 00:00      
                                                                              Read up on phase detectors and separate from lgic detect            01/01/70 00:00      
                                                                                 Yes, I know about phase detectors, and in this case...            01/01/70 00:00      
                                                                                    Learn, and it will not be irrelevant anymoer            01/01/70 00:00      
                                                                                       This stuff is still irrelevant until you know the type            01/01/70 00:00      
                                                                                          And the type covered again and again            01/01/70 00:00      
                                                                                             For the purposes described by the O/P it's not relevant            01/01/70 00:00      
                                                                                                Already covered            01/01/70 00:00      
                                                                                                   Until you have a way of ascertaining the ins and outs ...            01/01/70 00:00      
                                                                                                      Obvious, but _you_ singled out propagation delay            01/01/70 00:00      
                                                                                                         various but still MCS-51            01/01/70 00:00      
                                                                                                            Difference hobby or commercial use            01/01/70 00:00      
                                                                                                               you caught a VERY important issue - and did not know            01/01/70 00:00      
                                                                                 avoid kicthen table            01/01/70 00:00      
                                                               there is no way in hades ....            01/01/70 00:00      
                                                                  Not even commercial testers are really commercial grade            01/01/70 00:00      
                                                                     emphasizing the above good post            01/01/70 00:00      
                                                                     I'd guess the application is a bit different            01/01/70 00:00      
                                                                        ah ...            01/01/70 00:00      
                                                                           Yes ...            01/01/70 00:00      
                                       It's always a tradeoff between time and money            01/01/70 00:00      
                                          e-bay??            01/01/70 00:00      
                                             If you find one and buy it ...            01/01/70 00:00      
   If you REALLY want one of these ... but one that works ...            01/01/70 00:00      
   not a defective chip, but ...            01/01/70 00:00
