Still More Mystery Hardware

Help!

I have some apple hardware that I just picked
up second hand and need help to identify:

--------------------------------------------------------------
(#1)
Printermate
Rev 1 by Advanced Logic Systems (c) 1982

I believe that this is a serial printer card, but
don't know what the pinouts are.   The connector
is somewhat like an old disk][  connector with two
rows of pins.
--------------------------------------------------------------
(#2)
Dumpling 64
by Microtek (c) 1983

Again I believe it is a printer interface card, parallel, this
time, but I don't have pinouts.  Again they are disk][ style.
There are also DIP switches on this board, but I have no idea
what they should be set to.
--------------------------------------------------------------
(#3)
APPLICard
by Personal Computer Products, Inc (c) 1982

I don't know exactly what this is but suspect [HOPE] that it may
be some kind of hard disk controller.
It has an EPROM in it labeled:  ROM Bootstrap v9.0 (c) 1982
Once again it has header connectors, but I don't know how they
should be connected.
--------------------------------------------------------------

Thanks in advance for any help.
