Personal Logic Analyzer

The PL/A 524 converts your IBM compatible PC into a 50MHz, 24 channel logic analyzer.  At this time, "Personal Engineering" was becomming a thing.  PCs and other low-cost electronics made it possible for hobbyists and experimenters to make and use state-of-the-art tools that were traditionally out of reach.

The PL/A Logic Analyzer  has 24 inputs that can be attached to any digital signals, and the results displayed on the PCs screen.

This is a valluable tool for troubleshooting and debuging digital circuits.

I don't remember how much we sold it for, but it was cheap.  Trouble was, nobody wanted cheap.  The vast majority of postential customers didn't care how much it cost because it was paid for by the company, not the user.
