Dec (Digital Equipment Corp) clone vendor K&T or KT boards

I encountered and my acquire a pile of DEC boards from KT or K&T (one paper tag mentioned this).

It's a vendor that currently doesn't ring a bell (will update this when figured out).

There a large pile of probably custom system boards, and a board with 32k x 17 bits + 64k x 17 bits  (4116 and 4164 chips resp.) in the pile.

Also several boards with 6820 and 6800 processors on  Flip Chip boards.

All are hex high boards.  Some have 4 populated connectors with two flip chip spots blank, some have 5 (skipping one of the possible power slots).

Photos below, taken quickly today.

Train Dater Die, Cosmo Stamper, Ticket validator, Ray Weart, North Shore Restorations.

The validators have a number of terms, this covers them for search purposes.

Varian 620i

Seems to be pickings from a printer or graphics subsystem.  Trying to puzzle it out.
