Looks like Ian Primus has laid claim to it and since he's local, it is a more preferable arrangement. Curt James A. Markevitch wrote: > I've been travelling and just got back.

Still more VCF videos

by evan＠snarc.net

Lots of videos from last year's VCF East are on YouTube at our museum channel: http://www.youtube.com/user/MidAtlanticRetroComp#play/all ... this includes the two-minute montage, a short clip of our Straight-8, and more. T-minus two weeks until VCF East 6.0. I'm stoked!

Computer History Museum slideshow

Old news to the New World Colonials on here, perhaps, but for we Old World types - or indeed any Antipodeans - this is an interesting gallery, with some rather ill-informed captions. http://www.pcauthority.com.au/Gallery/153867,computer-history-museum-photo-… <http://www.pcauthority.com.au/Gallery/153867,computer-history-museum-photo-…> -- Liam Proven ?

Can't wait two more weeks until VCF East 6.0 ..... me either! Here's a video montage of the exhibit hall from last year's show: http://www.youtube.com/watch?v=0mNXrKjiD78 .... enjoy! PS - We're at 20 exhibitors and counting - it's going to be the biggest VCF East yet! www.vintage.org

My intentions are to develop an interface to a PC to implement some virtual storage devices. If all goes well I'd like produce these cards in small volumes and so I'm keen to use off the shelf components as far as possible. The main problem of course is the bus receivers and drivers as these are pretty much unobtainable as far as I can tell. I'd therefore like to find suitable alternatives. Does anyone have any suggestions of suitable devices? Examples of chips I'm looking to replace are the DEC 8881 driver, DEC 8640 (or DEC 380) receiver. Thanks, Toby Search the CCtech archives for 'unibus transceiver': http://www.classiccmp.org/mailman/mmsearch/cctech?config=cctech&restrict=&e… Alternatively google for 'Am26s10cn'. It is about the closest to a true unibus transceiver that is still available (in a DIP package even). TI makes it, available from DigiKey. Don

Looking for measured power consumption of some old DEC minicomputers

by jgkoomey＠stanford.edu

Hi Zane, Forgive me if I'm not using the right method to reply as I'm new to the list. I didn't see Al Kossow's post in the archive. I think that including a peripheral might make sense if it were a big hard drive but not if it were a printer. Anything that is involved in core computations for the computer (as opposed to input or output) would be fair game. I know that these computers do vary widely but I'm willing to go with what machines are available for metering. The big uncertainty is in getting measured power use of any kind. The exact boards that are installed are not as critical. Any ideas for folks who might have metered their PDPs? And the key thing to keep in mind is that the trends in performance swamp any errors in the measurement of power use, so I just need to get in the ballpark on power for the data to be useful. Defining system boundaries is important, so the peripherals question is one that we'd need to discuss. Thanks, Jon On Thu, 27 Aug 2009, Al Kossow wrote: > Also, are you just talking about the CPU, or including peripherals? I was wondering this myself. This is an interesting topic, but it might be difficult to define a "standard" configuration for these machines. Even the contents of the CPU boxes can vary widely. I suspect that many on this list are like me and tend to limit what what boards are in our CPU's to just what we need. How many people really need the CIS (Commercial Instruction Set) portion of the CPU in their PDP-11/44's or 3 Serial boards for terminals? I also limit the drives to what I need typically (I've even been known to unplug CD drives on PC's). Zane Hello all, I'm doing an analysis of trends in the energy efficiency of computation over time (for details, see the first report listed at http://www.intel.com/pressroom/kits/ecotech) . I'm using standardized performance measure from previous work by Bill Nordhaus at Yale, and then attaching measured power use to the machines for which Bill estimated performance. I got measured power data for the DEC PDP-1, PDP-4, and PDP-8 from Gordon Bell (now at Microsoft, who worked on these machines back in the day) but am seeking measured power use for some of the other machines listed below. I understand that some of these machines may not be unitary and so power measurements are more complicated. I'm interested in the sum of power consumption for the CPU, memory, and hard drives for typical configuration of the machines listed below. Ideally, this power measurement would be taken when the machine is running full bore, but I'll take what I can get. Does anyone have any measured power use handy?

DATARAM unkown memory board help

by stephane.tsacas＠gmail.com

Hi, I have this DATARAM board, which only says "40734 rev B" on the solder side. It's populated with 2 x 18 MK4116 memory chips, so I guess it gives a total of 32 Kw. I don't know how to map it correctly in my PDP 11/05 address space, given that it already has a 4kw core memory mapped from 24 to 28 K. The 11/05 originally came with this setup, but I can't locate the MOS memory by LOAD/DEP/EXAM values every 4K from the front panel. The red led goes off when the bus is reset, and the green one is on. Does anybody know this card and the jumpers settings? Picture: http://www.conservatique.com/pdp/pdp-1105 <http://www.conservatique.com/pdp/pdp-1105> Thanks! -- Stephane http://3w.posterous.com

Looking for SGI ONYX Keybaord, Mouse and front cover

by g-wright＠att.net

Anyone have some Onyx parts out there. These are Desk side units. One needs just the drive cover the other is missing both the front and back covers. I also would like to find some Keyboards and mice for the same. - Thanks, Jerry
