> From: Devin Davison > This past week I managed to pick up a pdp 11/23. 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? Noel

Logic Analyser Advice

by robert.jarratt＠ntlworld.com

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: http://www.ebay.co.uk/itm/291753390848, are these likely to be suitable alternatives? Thanks Rob

Tektronix Terminal Emulation

by dj.taylor4＠comcast.net

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?

DEC DW11 information?

by derschjo＠gmail.com

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: https://www.flickr.com/photos/25143643 at N07/32505083723 It's a piece called "A Mystery to Myself" by Keith Tyson. http://keithtyson.com/work/a-mystery-to-myself/ There are more pictures from this showing at a different galley: http://www.davidrisleygallery.com/exhibitions/keith-tyson2 -- Liam Proven ?
