Hi everyone

I need heko finding datasheet + infor for these chips:

7604
7628
7606
7610
7602

They also have 14473532 printed on too

They come from an old mainframe memory computer from 60's or 70's (not sure) there for im sure they are RAM but really want data sheets :)

Thanks,
Robin

maybe try searching Ebay for the vintage ICS... perhaps the numbers you have listed are date codes.
7604 4th week of 1976
7628 week 28 of 1976.... Et cetera.

I think they are date codes also. Have you got pictures? You think they are RAM but those numbers do not correspond to any series of RAM chips from that era that I am familiar with. If they are RAM then it is likely they are x1 types so they would be arranged in rows of 8 or 16 chips. There were no RAM chips of any size prior to about 1970.
