Huh. It's not supposed to do that.
The lowest data bit of keyboard seems to oscillate when I press the N key, and sometimes that means the bit appears high when it should appear low. This results in typing an O instead. Every other key seems to be reasonable consistent.
What's also not consistent is that sometimes I get double key presses, which isn't great, but I can't seem to capture the strobe doing that. I need to see what it's doing on the scope in order to get an idea of what I'm trying to fix.
Yay early 1970s keyboards...
