Found the KBD Hackin' NoteBook, but no joy, it was a PC Matrix I was working on for a Custom Layout USB KBD. :-/
Scanner's not up yet . . . :
. . . so it's just piccies for now, enjoy! 
Forgot about some of the details as well. :I The 1400's got a very interesting Flex Circuit Layout! It's all one piece and it folds back upon itself, looks like 11 signals make the 180 degree transition from top layer to bottom layer.
No, I'm NOT cuttin' mine up to scan it!!!!!!!!!!!!!!!!!

Figure out the general layout from the piccies. Then, when you think you've got it "right," buzz the connections with a continuity tester, on an unhacked 1400 KBD, to determine the accuracy of your matrix layout/pinout. [] ]'>
