Some of them certainly are. Others look to be from -6's or
older -10's.

>All cards listed are in neither the DEC field guide or Doug Jones' Omnibus
>module guide.

Mainly because most are not Q-bus, Omnibus, nor Unibus boards. I'll
try to remedy that :-).

>B014

Are you sure it's not a B104? That's 4 inverters.
My memory is real hazy on low-numbered B modules, but most are from -6's
or -10's.

>G180

Low density R/W amp for RK04 DECPACK drive.

>G208

PDP-8 Inhibit driver - replaces G205

>G603

Memory selection matrix for PDP-6

>G808

Power supply control for PDP/8

>G938

RK05J Head Position Servo

>M051

Don't recognize this one.

>M111

Totem-Pole NAND gates

>M113

More Totem-Pole NAND gates

>M206

Don't recognize this one

>M302

Two one-shots

>M3118YA

This is a CXA16, a 16-line serial async multiplexer as found in some
DEC terminal servers.

>M506

Bus receivers, I think.

>M624

Bus drivers for PDP-8's and -15's.

>M7164

First half of a KDA50

>M8956
>M8957

These two are out of a TU78 formatter.

>R002

Common Cathode diode network

>R205

I'm pretty sure this is a register module from a PDP-8

>R210

PDP8 Accumulator

>R211

MB, PC, MA for PDP8

>R220

3-bit SR for PDP-8

>R405

PDP-8 clock module

>R650

Don't recognize it

[General note: S modules are generally R modules with clamp loads]
>S111

5 mA clamp version of R111

>S181

DC Carry Chain, 6 diode gates and inverter from PDP-8

>S202

5mA clamp version of R202

>S203

5mA clamp version of R203

>S603

5mA clamp version of R603

>W026

PDP-8 connector card

>W103

I think some kind of bus transceiver from a PDP-10.

>W640

3 pulse converters

>W707

Book says "Teletype Transmitter, 8 bit, 2 unit stop code only". I
think from a PDP-10.

>W998

Blank piece of vectorboard, used for custom circuits.
