Oh!! A PCjr question! Oh oh!!!
A stock PC keyboard will not hook up to the Jr because the Jr is,
well goofy. There is a technical description behind goofy and
I can take an hour to paraphrase the technical reference manual,
but not right now ...
You have three options:
[1] Find a real PCjr keyboard, either the original chiclet
or the improved keyboard. These show up on (gasp) ebay
once in a while, without the rest of the computer.
[2] Find a pseudo-real PCjr keyboard - Keytronic made some
really nice keyboards and numeric keypads for the PCjr.
[3] Find an adapter. Several companies made these, but I
think they are very rare. I've never seen one, and I'm
sure that not many were sold.
Good luck. PCjrs are wonderful little machines. Here is my

PS: The gun discussion is rediculous. Please stop. Wading through
the digest is hard enough. Wading through it when half the
messages are about gun control and life vs. death situations
is even more difficult. A newsgroup or discussion list probably
is not a good place to discuss this, especially a discussion list
dedicated to classic computers!
