Sheesh!!
Well what a response.
This stems from my (so far) successful major over haul of my PDP-8/e.
I found one failed 7474 and one failed 8881 – replaced and now working.
I think I have the rim loader toggled in and will attempt to send a paper tape

I have an idea to produce an MM-8 clone using RAM that acts like core when
turned off.
Can anybody suggest a chip that will do this?

Went to toggle in the RIM loader – huh !
Memory address 04 stuck low.
So either try another 4k core (after changing the jumpers)
or...
Trace the signal path.
What do we think?

Unless you have an oddball SLU, this is not true -- what do you have
installed? The earlier M8650 and the later M8655 can both be jumpered for
higher baud rates.

Hi All
Seasons Greetings..
My PDP-8/e was long due for a major overhaul.
1. So everything out
2. Big Hoover job on the Omnibus
3. Bring up on Variac – No smoke
4. Check PSU volts. – All OK
5. Power off
6. Install minimal System – Front Panel, Three CPU cards, RFI shield, 4k Core
and Bus
I have a large library of inlay panel pictures.
I’m sure I did some drawings with text when I did the blank panels. (Just the
holes for the lamps)
I’ll have a look. If not I’ll match a font to a picture.

The machine is identical down to the colour and the tape reader.

Hi
I worked with DIGICO’s in 1974.
Is it red?
Does it have a manual pull through paper tape reader?
Was it made in the UK?
I am most interested

There were plenty of real PDP-11’s that found their way to Russia.
Often through front companies in say Vienna.
