4003 is a shift register, for control the I/O signal.
I bought this one only on eBay, so I don't have full calculator board. |

Should not be a calculator. As far as I know, it is from a RACAL DANA 9000 counter. _________________ Tracing 4004 all over the world |

Yes, it's just a kind of scrap board
But it has INS4003, and can cost $10 |
