All ? Now that I have a running 11/03 (through the Heathkit HT-11 I bought) I thought I?d try to get something running other than XXDP using the TU58 emulator. Malcolm Macleod has a quick walkthrough of how to make this work with an 11/23 and the TU58 emulator from Will Kranz (http://www.avitech.com.au/pdp-11-03/make-tu58-rtv4-image.html). Even though the tutorial is for the 11/23, I think that the 11/03 can run RT-11 from an RX01, and the H11 came with an optional custom version of RT-11, so I feel that it should theoretically work. I followed the tutorial and it reads the image but barfs at some point and the CPU halts. Not sure why. Has anyone tried this?

VCF Midwest Dates Set: Sept 10-11 2016

by silent700＠gmail.com

Planning for the 11th annual Vintage Computer Festival Midwest shall begin in earnest in early April. But since the dates have been locked in for some time, there's no harm in getting them out early. Returning to last year's great new location, this time with an extra room and even more Visio-driven planning, VCFMW will once-again be *the place to be* for retro-tech enthusiasts in the Midwest! In an effort to accommodate as many schedules as possible, our dates have shifted back a bit vs. last year. So please make a note on your calendar, VCFMW 11 will be the weekend of September 10th and 11th, 2016. As always, the fun will begin on Friday night with early load-in, group dinner(s) and general frivolity. Many details are yet to be worked out, but we envision a slight schedule change (later Saturday and earlier Sunday start and further optimization of the room and table layouts. The old vcfmw.org URL still works, as well as the new page from our friends at the Vintage Computer Federation: http://vcfed.org/wp/festivals/vintage-computer-festival-midwest More info will be added in a few weeks, as well as a new registration page for tables, talks and vending. Please hold your tabling requests until the announcement next month (I have to draw the chart first!) Every minute of last year's show set a new standard as we went into our double digits. We look forward to seeing you all (and more) again this year. -j

Best name for PDP-11/05-10

The ones I have found online are: DEC-11-H05AA-A-D Jan, '73 PDP-11/05 computer manual DEC-11-H05AA-B-D Sept, '74 PDP-11/05, 11/10 computer manual DEC-11-H05AA-B-D Supplement 1 July, '74 PDP-11/05, 11/10 10-1/2 inch mounting box and power system DEC-11-H05AA-B-D Supplement 2 July, '74 Description of data paths module M7260 revision M DEC-11-H05SS-B-D Jan, '75 PDP-11/05-S, 11/10-S system manual EK-11005-TM-003 April, '75 PDP-11/05, 11/10 computer manual (The 2nd-4th are in a single file.) > Compared to the one at bitsavers it for example include an appendix > related to some minor modifications that had been done to the CPU board > set. The ones that are available seem to be pretty comprehensive coverage of the 05-10, the 05N-10N, and the 05S-10S. If yours has some significant material that is not in the others, then please scan it. Otherwise, it may not be worth the trouble (especially if you do not have an auto-feed scanner... :-). > the system came with an extra 5.25 inch memory box. Identical to the > CPU but different backplane for three more MM11-L modules Right, that's the ME11-L, which is an MF11-L backplane in a 5-1/4 box; it normally came with one MM11-L board set (16KB) installed, and one could add two more sets.

Pdp-10 emulation

by jnc＠mercury.lcs.mit.edu

> From: Tedd Martin Vazquez > After reading I believe using TOPS-20 I will have more to explore Actually, as an operating system, ITS is far more interesting (virtual devices, etc) - but it is indeed a pretty steep learning curve to start using it. So I agree that TOPS-20 is the place to start. Noel

Looking for a 2W 1 ohm fusible resistor

by witchy＠binarydinosaurs.co.uk

Morning folks (other timezones are available) One of the casualties in my expiring VT100 PSU last weekend was a 2W resistor named R22, or at least it seems more dead than its twin at R47 which gives a steady reading on my DMM. Seems that they're surprisingly difficult to find these days with none of the main parts stockists having any. Anyone got one or two lurking in a bits box somewhere?

Has anyone heard from Vince Briel lately? I've bene trying to get in touch with him for some Micro-Altair artwork.

Paging Toby Thain [was RE: PDP-10 programming [was RE: Dumb Terminal games (was Re: Looking for a small fast VAX development machine)]]

by RichA＠LivingComputerMuseum.org

Hi, Toby, I answered your private note, but Outlook/Exchange informed me this morning that it would not send the message for 48 hours and so was giving up. I just don't want you to think I'm ignoring you. My answer was that it's not for me to say, but the author is a friend.

Unidentified DEC gear available, NSW-AU

by jwest＠classiccmp.org

DEC Gear available. Unlike most dec gear, I must admit that I can't identify exactly what this is. Several racks, I was guessing AFT or Instrumentation Testing. Looks like one or more cpu or expansion cabinets in some of the racks, and some DEC AD/DA interface stuff. I was left with the impression that there may be one or more racks that are not shown in the pictures provided. I was told that racks are in "several different buildings on the estate" (residential). The first rack looks to be in very bad shape (perhaps a power supply), but the other racks don't look so bad. I am not sure that I can get more pictures from the owner, but will try. I think that in order to get pictures of the fronts (what we all probably want to see), the owner would have to move stuff (and them) and would rather not. The equipment is located in NSW, Australia. It sound like they just want it to go to a good home. If someone is local to NSW Australia and wants to spearhead going onsite to take a closer look for others and/or pick up the gear themselves, let me know offlist and I'll give you the contact info. To those on the list that aren't down under - any ideas what this is? Pics are temporarily at http://www.ezwind.net/nsw-au Best, J
