> From: Johnny Billquist > All I can say is that I did a number of RSX SYSGENs on that 11/34, and > it truly looked just like an 11/24 from a software point of view. The thing that I wonder about it, for that to be true, is something that someone (sorry, to lazy to look in the archive to give proper credit) pointed out, which is that that CPU is only two boards, and the memory management, including the PARs, is built into one of them. So how could one extend a PAR >from 12 bits to 16, when there's already 12 bits buried deep inside the CPU? That's the part that I can't work out... > I'm hoping that Update ... still have the documentation around. You and me both! :-) I have this dream of one day having an 11/45, with the Enable and the optional cache. Now that would be a sweeet machine: most of the capability of an 11/70, but a lot less power draw. But I'd need the documentation to see how to connect it up! :-) > Every time this comes up I really want to go searching for manuals... > :-) Please do! :-) Noel

Qbus split I&D?

by jnc＠mercury.lcs.mit.edu

> From: Johnny Billquist > One more thing to check this summer... OK, if you can, that would really be great; if either i) it's still together, or ii) there are pictures, it would fill some of the key knowledge gaps. In particular, i) what kind of backplane is it plugged into, and ii) what is the UNIBUS edge connector on the card connected to... Noel

VCF Midwest 10

by silent700＠gmail.com

The silence may have led you to believe that it was all over. Oh no... The 10th Vintage Computer Festival is a GO! Bigger, bolder, nerdier than ever, a wonderful way to tack on our second digit, VCFMW10 will be held August 29-30 at the Holiday Inn Chicago-Elk Grove Village. A remarkable convergence of amenities and price have come together in this spot. Among the features: - A single 4550 sqft banquet hall - at long last, VCFMW and ECCC shall truly be one! - First-floor facilities - no more elevator rides or Level of Discharge! - 11'x12' loading doors that open direct to the parking lot - you could drive a truck right into the ballroom, but don't! - A separate room for talks, videos, quiet time, etc - like we're a real conference or something! - No (known) conflicts with holidays, wives' birthdays or other local events! - The quaint, vaguely Blade Runner-esque surroundings of industrial parks, truck depots and factories - just the way we like it! - An on-site restaurant, pool, exercise room, outdoor firepit/smoking area, shuttle buses to/from the airport and Woodfield mall, close proximity to fast-food and the two greatest Chicago eateries, Portillo's and Lou Malnati's! (Seriously, those two alone are reason enough to attend.) I have updated the http://vcfmw.org web page and FAQ with most of the information we have so far. Please give them a read before posting questions. Hotel room rates will be slightly higher than last year's $79 at the Fairfield Inn; I am still negotiating the block rate. Due to the restaurant being on-site, there will be no continental breakfast. Sorry :( Now the hard sell: all of this geek-luxury does not come without a price. Some of you know that the deal we had at the Heron Point was extraordinary and unheard-of in the event hosting business. Since the HP no longer rents to the public, we were faced with the choice of resting on our successful nine-year record or figuring out a way for the show to go on. And go on it shall...with your help. Without getting into specifics, the cost of putting on VCFMW has more than doubled - and we are getting a bargain if our comparison shopping is to be trusted. Donation links have been set up on the main VCFMW page for PayPal and GoFundMe sites. Please use the GFM only if you do not have a PayPal account, as GFM charges us a fee. If you'd prefer to donate in person, contact me directly. I will get you a receipt (sorry, we're not a 501.3c yet, so it won't be tax-free.) The main site features our non-patented Donate-o-Meter which will (more-or-less) track our progress. We have a lot of time to reach our goal as payment is not due until the day of the show. Extra money raised will be either spent on bonus features for the show (more space, pizza bar, etc.) or put into a fund for next year. We will engange with the community as much as possible before making any decsion regarding extra funds. There will be much to do between now and August - a new floor plan to design, tables to allocate, speakers to recruit. But our first big task is one where everyone can help: let's get the word out! Many of you are on forums that I am not, so spread the news: the show will go on! -j

Ebay GT-40 in the Netherlands

by jws＠jwsss.com

DEC-Digital-1972-GT40-vector-graphics-system-PDP11-PDP-11 http://www.ebay.com/itm/231477915161 If I could afford it I wouldn't sweat the shipping cost. I think someone had posted what board did the graphics. Has that ever been given consideration for being added to SIMH for the 11? I'd love to run Lander, which I think is running on the system as shown. To Al: There was also a system like this at USL, which I wish had been conveyed to you. I suspect it was not. There was a new in the box replacement CRT because someone had had the system halt and burned the phosphor. You had to watch the system and never let the dot stop. If it stopped at a spot on the phosphor in the on position, you'd etch the phosphor. Ours (USL) never ran anything but Lander, so until someone with a project came along, we were saving the tube. The burn didn't affect lander much at all. thanks Jim

by martin＠shackspace.de

Hello! The EPROMs are labeled 07595-18045 and 07595-18046. We suspect some bits have toggled. Can anyone do a dump for me? It's for the 7596A of our local hackerspace. Greets, Martin -- Martin Peters martin.peters at news.uni-stuttgart.de

360/50 microcode listing

by aek＠bitsavers.org

CHM was able to obtain volumes 18-20 of the IBM 2050 drawings, which are the microcode charts and ROS dump. I got them scanned and uploaded yesterday to http://bitsavers.org/pdf/ibm/360/fe/2050 This was one of the things that I had been trying to locate for a while now.

PDP11GUI v1.46

by j_hoppe＠t-online.de

PDP11GUI is at v1.46 now. Among others I fixed an annoying bug, which prevented proper terminal output when running certain diagnostic paper tapes: Filling <NUL> chars were sometimes interpreted as backspace! Load from http://retrocmp.com/tools/pdp11gui As ever, any feedback is welcome, Joerg
