[Exceptionally top-posting...]
There are two modules each containing eight pulse transformers. That's it.
The left module has the cover removed.
No memory, no register. This board is from 1971, so it would contain some
TTL FFs or RAM (e.g. 7489) for registers.

Hi Josh,
I saw your posting on the 23rd Jan 16 regarding Bull DPS 6.
We are based in the UK and actually run 4 working DPS6 systems in the UK.
Any system (in its entirety or parts) we may be interested in if compatible
with our existing system.
Do you still have it?
Many thanks,
Julian

Tried my M7838 EIS this morning. It is bad or there is a config/jumper
issue to investigate. With the EIS installed I cannot boot RT-11 5.3 nor
UNIX 6.
The good news is that when I attempt to boot UNIX 6 I get a different error
than before. Now, when I run rlunix at the ! prompt, the system res
I think it's only mostly dead :)
Sorry :(

When installing the KE11-E, you have to remove a jumper on the CPU's M7233
module. See pg. 2-1 on the KE11-E/KE11-F User's Manual (EK-KE11E-OP-001),

It's pretty obvious to me that there are several turns on each core.
Given the PCB fab date (10/73), there were better methods for keeping

GCC does still have a pdp11 backend today. It doesn't seem to be very
actively maintained, and how well it works nowadays

Not V6 (the subject of the current discussion); the C compiler of that era
