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...

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...

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...

I’ve recently put a new page online on the site. It hosts a basic outline on different techniques to enable one to reverse engineering a PAL, and produce a modern equivalent. Right now, there are about a dozen...
