Hi there, Been lurking (and learning) for a few weeks here. Lots of interesting topics for sure. Do any of you have inverse assemblers for the HP1631D logic analyzer ? Specifically, I am looking for the files that go with the 10342B interface (RS232/422 and HPIB capable) but I'd also be interested in inverse assemblers for any CPU. I have one to date. BTW, the 1631D is connected to my PC using an HP disk drive emulator written by a fella from the Yahoo HP group. The files are therefore loaded and saved right from my PC via HPIB. The code is pretty new but already functional. This meant reverse engineering the CRC being sent from the original HP driver over the HPIB link - no small job in itself. This is my second attempt at posting on the list - I apologize if this ends up being a duplicate post. Regards to all, Benoit Robert
