[vcf-midatlantic] What IC Do I Have Here?

Greetings! AY-5-4007A I actually have five of them. I'm assuming based on the part number that they were made by General Instruments. They are 40 pin 0.6 inch dual in-line units with a white ceramic case and not-gold pins. All five I have are dated the fourth week of 1974. I can find no references to this exact part number. There is a known AY-5-4007D, which is a 24 pin seven segment display driver. I would guess that a indicates the first in a series. Along that line, I'm thinking they might be bit-slice ALU chips, but that's just a wild guess. Regardless of what they turn out to be, I have absolutely no use for them, so let me know privately if you would like to take them off my hands. TIA Joe Giliberti
