[sdiy] flip-flops

[Mountain Man]

No, it's not about going to the beach!  It's about trying to get the
circuit-du-jour to sit up and beg!  I'm working on a Scott G circuit,
that contains 4027 flip-flops.  I haven't been able to get the flip-flop
part to work, so I finally ran some stand-alone tests on the 4027.  I
have the chip powered using -12V (as ground), and 0V, since that's what
the circuit calls for.  I'm feeding the chip clock pulses that alternate
between -12V and 0V.  R and S are both connected to -12V, and all unused
inputs are as well.  My digital logic book claims that when both J and K
are set to 1, the flip-flop should change states on each clock pulse.
I've connected J and K to 0V.  I see notQ changing state, between 0 and
-12V, on each positive pulse (0V).  Q, however, holds steady at 0V.  Can
someone tell me why Q isn't the complement of notQ, as expected?  I've
fiddled with this for several hours now, and I have no idea how to
proceed.  BTW, I spent quite a while looking for a 4027 datasheet on the
web; if anyone has one, I'd appreciate an email  :)

Thanks,
