I used to own the RB5X robot company.  I thought these chips were  long gone, and I found a stash in my parts the other day. These are NOS from 1983, still in the original tube.

If you are looking at this chip, I will assume you know what it is and how hard they have become to find, especially new.

Both the Votrax SC-01 and SC-01-A were used in many products, below is a list of some of them.

I am a part time, fun item seller.  I try to describe my items as best as possible but I am not an all knowing expert.  I pick up things from many places and test the best I can. If there are any questions, or you need any more details, please ask BEFORE bidding. If some thing is not functioning properly, or you feel I did not describe the item correctly, please contact me before leaving negative feedback.  I am always willing to work with you as best I can.

I will combine shipping whenever possible.  If you purchase multiple items, I will box together if I can, and refund the overage.
