Incredibly, at least one PCjr actually worked right off. I bought a bunch of PCjr stuff from someone ages ago, three computers and a bunch of random other junk from the big Computer Reset sale. I'm cleaning out my junk room and just reached the PCjr pile, or one of them.
First keyboard didn't work, and the computer made a frantic arrhythmic beeping until I swapped in another...this one a chiclet.
Everything's coming up Milhouse.
