So for today ladies and gentlemen, I present a teardown of an HP/Agilent logic analyzer cable. I think this is part number 16715-61601. This cable is used to connect one of a series of 40-pin compatible modules (many of the 167xx series, but not...

It’s often useful when trying to understand, debug, or reverse engineer a system to put together a timeline of operation from beginning to end. The result is a series of events where something happens first, then something else, perhaps some...

In order to properly reverse engineer a PAL, you need to correctly identify which pins are inputs, and which pins are outputs. This in some cases is trivial because some of the PAL’s pin functions are fixed. Let’s look at the example of...

Of all of the different techniques this one may be the simplest but also the most important. When you’re trying to reverse engineer something, understanding the system is key to unraveling the black box which is the PAL. You need to understand...

Rom Dumping Dumping ROMs is a pretty common practice in the space of reverse engineering, and many eeprom readers are cheap, easily available, and there’s really not much to them. Plunk your ROM chip in the reader, press, go, and you have a...
