Ah, good point. In theory the keyboard buffering applies to the $200
area of AUX ram if I'm not mistaken, but I'll check it out - I have the
reference manual somewhere, at least the original one, which won't
cover any changes made in the 4 other IIc firmware revisions.

Anyone got a 2nd edition IIc tech reference? I can't validate it with
an actual machine, as my only IIc (a ROM04) is 1500km away

Sure... The other thing I have to check out is the IIgs, but to be
honest I'm relatively unconcerned if my code won't run on it.
