This is also posted in the PDP-8 google group. Please forgive me for any redundence.
I have recently acquired a running (I haven't received it yet so I don't know for sure) PDP-8/E and what looks to be a PC05 (I haven't actually received the system yet so I'm not sure).
The PDP-8/E comes with only one 20 slot H919 Omnibus back plane. I have previously acquired a separate H919 back plane which I would like to add to the PDP-8/E case.
The assembly drawing for the PDP-8/E calls for some kind of foam to be placed under the back plane. Does anyone know what I should use? Should it be conductive or just something to keep the pins from shorting to the case itself.
Does anyone know where I can buy, beg, borrow or steal a pair of M935 Omnibus Bridge sets?
The PCP-8/E has the following boards already installed:
M8330 Timing Board
M8310 Major Register Control
M8300 Major Register
M837 Extended Memory/Time Share Control
M8650 Asynchronous Data Control
W966 Wire Wrap Board (unknown circuit)
M840 High Speed paper tape reader/punch control
M849 RFI Shield
G104 4K Core Sense/Inhibit
H220 4K Core Stack
G227 4K Memory X/Y Driver
M8320 Bus Loads/Terminator
I will be adding an M848 Power fail board that I already have.
Does anyone know of a way to interface the PC05 to the M840?
Also, I am looking to acquire the following boards to add to the system:
More memory (core or semiconductor)
M8340 EAE Board 1
M8341 EAE Board 2
M868 TD8E DECTape Control
M8360 Data Break Interface
M8357 RX01 Controller
M7104 \
M7105 | RK05 Controller
M7106 /
Additional Hardware I would like to add. Most of this is just a dream because of lack of availability of the hardware and my limited budget.
M935 (I need a pair of these as soon as possible so I can add the second 20 slot backplane)
TU56 Dual DECTape Drive
RK05 Disk Drive
RX01 Dual Disk Drive
TC08 DECTape Controller
H960 Rack Cabinet w/PDP-8/E name plate preferably.
