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.

Sounds like a bussed resistor network, 13 1kohm resistors.

    \$\begingroup\$ Maybe. Easy enough to suss out with a DMM, just look for the 1k resistors. \$\endgroup\$ – Ignacio Vazquez-Abrams Oct 24 '17 at 5:38
