I figured you were, but no problem. Here's the simple gated
oscillator: (view in Courier)
+--------[0.1µF]----+
| |
+--[1K8]-+ |
| | |
+--A | |
| NOR Y--+--A |
______ +--B NOR Y----+----3kHz OUT
ENABLE--------------B
"A" and "B" are the inputs of the two NORs, the "Y"s are their
outputs, and to make it run you pull the ENABLE input low for as
long as you want the thing to oscillate.
