Nice system; the CPU has the MMU and FPP, you've got what's probably a 256KB
memory card (an NS23M - documentation is available - depending on the chips,
it can be 64KB or 256KB - if the former, let me know, I'll swap you a 256KB
one), and I think the pair of quad cards are probably an RLV11. Not sure what
that off-brand dual card is - maybe a ROM of some sort?
I wonder what the card on top in the chassis is? It looks like it has way too
many chips on it to be just a power supply board - but I can't figure out what
it could be. Anyone know?

I am downsizing and have an HP 2105 available. It?s been stored well, but I cannot vouch as to its operability. I do not know off hand how much memory it has.
It is located in Saint Paul, MN.

I finally managed to pick up a logic analyser for a price I could justify.
It is a HP1630G and it comes with a number of pods. However the pods do not
seem to have the actual wires/probes. Is there a separate part number for
these that I should look for. There seem to be quite a few items like this:

alternatives?
Thanks

I'm trying to return to the computing days of yesteryear when people
hooked graphics terminals to VAXes.
I don't have a Tektronix graphics terminal but I do have a MicroVax II
and a laptop running Debian Linux. Up to now I've been using the laptop
as a console device and connecting to the Vax using minicom. I thought
that the laptop would be a natural as a Tektronix type terminal.
On the MicroVax I have just started with PGPLOT and MIIPS, which are
scientific plotting packages that run on Vaxes.
I would like to use the laptop to emulate a Tek terminal connected to
the Vax through a serial port, but there doesn't seem to be anything
available to do that. Does anyone know of such a thing?

Hi all -
Anyone have any technical information (manuals, schematics, etc.) for
the DEC DW11 UNIBUS->QBus interface? I'm curious to know what it's
capable of and what the requirements are, especially on the QBus side of
things. What kind of backplane is required? I assume it doesn't
support 22-bit QBus devices given the age of the interface (and the
complexity required to do so), but does it handle 18-bit devices, or
only 16?
I haven't found much technical information on it at all. Anyone have
any details to share?
Thanks,
Josh
Since, to my pleased surprise, this has been a runaway hit on
Facebook, I thought I'd reshare it here.
My friend Roger took a picture of this sculpture at the Jerwood
Gallery in Hastings on the south coast of England:

It's a piece called "A Mystery to Myself" by Keith Tyson.
