Well, I should've consulted that.  I didn't forget it exists.  Clearly,
I didn't recall any with that defect.  I remember some had the keyboard
bit permanently set.  But, for an emulator, I'd still argue they should
implement the "correct" method. ;-)  How common are some of the problem
machines we found anyway?  IIRC, probably don't, it was my, yours, and
Wolfgang's obscure collection ... Or, Steve? Alexei?  I.e., this was not
what we could call an "excellent" sample selection of machines.
