Cleaning out some OLD (30-40 years) parts drawers, I came across a few of these parts:
- 14-pin DIP
- package is 3 layers, black layer in between 2 white layers (ceramic ?)
- marking says "STACKPOLE 14-13-1-R 1K" and "7711" perpendicular to that
Nothing useful googlable. Doesn't really matter - I'm just curious. I vaguely remember it's integrated resistors of some kind.
