I have to
admit, even though I'm not a PC fan by any means, I found the PCjr
 fascinating. It didn't deserve the fate it got (though it *did* deserve a
 better price point than it was saddled with). 
 I have several, as I've always found them fascinating:
 - They had diagnostics, BASIC, a "game" and other stuff in ROM 
 
I am trying to find a reason to keep my PCjr, so it comes down to this -
were there any mainframe communications developed for the thing?
Hey, even the 5100 could talk to an S/3.
