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.
