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
I meant to include a photo. Here ya go On Thu, Jan 13, 2022, 4:06 PM Joseph Giliberti <kd2dhp@gmail.com> wrote:

It's a 7 segment display driver. Here's the datasheet: https://www.mikrocontroller.net/attachment/454578/AY-5-4007.pdf dud This email is free of malware because I run Linux. On Thu, Jan 13, 2022 at 4:32 PM Joseph Giliberti via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:
