I'd guess that it was mostly for DECserver 500/550s to boot off of a
VAX/VMS host.
So... yes, a MOP server running
The boot ROMs for uPDP-11 contain loaders for XH (ethernet) was there any
kind of standard for the server?
It tries to load from a MOP DL server and I have modified mopd from NetBSD
to respond and load 2.11bsd a.out. So I have a solution, but was curious if
there was some DEC standard.
That’s a great one! Best summary of this thread so far. Thanks for sharing.

The DEC PDP-11 Unibus Handbook identifies three standard ICs for use
when connecting to Unibus lines:
Bus Receiver - 8640 Quad NOR
Bus Transceiver - 8641 Quad
Bus Driver - 8861 Quad NAND
It seems to be generally

I just rescued a Cossor DIDS-400 terminal from ending up at the garbage dump.
Cossor was a UK company, that ended up as a Raytheon subsidiary, and the Cossor
DIDS-400 was marketed as the Raytheon DIDS-400 in the US.
My terminal is model no 402-2/C15, part no D/GA 800260, serial no 023,

What a fantastic rescue. I for one will be very

What a fantastic rescue. I for one will be very interested in our new

Hello Everyone,
We found a PDP-11 QBUS card cage with a KDF11 and some other cards (RAM,
ROM, some basic peripherals) which included a DSD-4140 card.
Unfortunately, the DSD-4140 is missing one of it's microcode PROMs for
some reason.
Does anyone else have one of these cards? It'd be

They come with the Salae logic analyzer, and are like the HP logic analyzer
clips
in that the wire is detachable, instead of the common style you can

That's almost certainly a DS8640; a quad NOR unified bus receiver. Data
sheets for the are readily available.

I am trying to trace the reason why the CPU on my Pro 350 is apparently
being constantly reset. I have reached a DEC 8640 chip. Does anyone have a
pinout for it, perhaps even a datasheet, so I can understand what it is
supposed to do and whether the pin is an input or an output?
Thanks

This was circulating in 1995/6. IBM had been shipping the very good
OS/2 for some years and Microsoft was trying to catch up. Someone did
a very nice parody.

foo, I forgot about the CPU board. the grid needs to be 67x86 :-(
