Can someone help me on info on the Bearcat BC-160?

I'm looking for an owners manual BUT I also want info on a
strange edge connector much like one found on the back of a
Commodore vic 20 or C64. A plastic cap removes to reveal
this connector but it's not marked.

It's also one of the few scanners from the early 80's with
100% electronic push buttons to control everything including
squelch and volume.

I searched the web but found very little except people looking
for a manual or info like myself. Must be a rare scanner.

This is what I do know:

Bearcat BC 160 with Search Mode
Covers 32-50 MHz 144-174 MHz 450-512 MHz
AC Power Only
