Fascinating! The schematics, alsa are not complete (there's no
information on the main ROM or keyboard, for example), At first I thought
it was thsoe bits that difered from the HP9100A, then I noticed the
flip-flops were included (and those are certainyl the same), so it's not
that. But still very interesting.
The flowcharts are, to me, eve more useful (perhaps becuase I already
understood the hardware). I can see I am goign to spend many hours
figuring out what those are telling me...
