561 7032 BP8S3600TS

16-Pin DIP's:
561 5594 BP866542TS

hey mate,

the only chance you would have is if you knew what make and model of equip they were manufacturered for. Then get a service manual for that unit and with luck you would see the the prop. part number and beside it the common device type name

good luck ;)

Ok davenn, thanks.
Yeah, I was using these things in the early 1980's, and I don't remember what for.
Maybe I'll get lucky here, and run into somebody who's got a better memory than me.

Was doing my annual search for unidentified parts on the internet, and ran across this
old post of mine (Google Search apparently likes Electronicspoint).
Still don't have an ID on these parts, if anybody new on this site does.
Thanks.
