For firmware writers CATALOG is a PITA because it is not just a simple load, but IIRC after each line it does an UNTALK/TALK/SECTALK sequence. So you need to keep the real File state as opposed to the LOAD command that just reads everything in one go. BTW the difference between LOADing a directory (or OPEN with secaddr 0) and an OPEN with secaddr >=2 is, that secaddr 0 loads the directory as BASIC file, >=2 actually reads the directory sectors from disk as if they were a file. CATALOG uses secaddr 0 - just with the UNTALK/TALK/SECTALK in between. Which is BTW a good test for your ATN and bus timing....
