Instead of a 4017 switching a 4066, why not use a 4518 controlling a
4051 analog multiplexer? That would keep the IC count the same,
but allow you to manage 7 GP2D12's using the original strategy (with
one of the 8 channels being used to detect counter rollover). Since the
4518 has two counters, by adding one more 4051 you could manage up to
15 sensors (!) with one more IC. Needless to say, I haven't tried to
build this ;-).

| Hi Steve, sounds good to me ! Try it and let us know, if it does work (why shouldn't it ?!?). Sad, but I don't own 15 (not even 7) Sharps. :( But, if changing the supply voltage (using a switch to chose between 5V from regulator (for sharps) or (...) (23 years ago, 2-May-01, to lugnet.robotics)
