VCF SE 4.0 Announcement

by earl＠baugh.org

Many of you may have heard about this already, but to make sure everyone knows, We are proud to announce the fourth annual Vintage Computer Festival Southeast (VCFSE) in Roswell GA. The Festival, on April 2nd and 3rd, features over 35,000 square feet of exhibits, museums, presentations, and interactive entertainment. Exhibitors are available for live demonstrations and offer attendees the unique opportunity to experience a true piece of technology history. New this year, a live auction offers bidders a chance to start or expand their personal collections. (Registration is still open, visit the link at the bottom if you'd wish to exhibit -- vendors are also welcome) The Festival offers very popular hands-on electronics projects for children and adults. Gaming fans will enjoy a wide array of vintage video game consoles in a retro gaming section, where visitors can play classic games. Gamers of all ages are encouraged to test their vintage gamer skills on a huge classic video game wall. This year, the Festival celebrates the 40th anniversary of Apple computer. Attendees will experience the complete history of Apple at the Computer Museum of America?s Apple Pop-Up Museum, a large, one-of-a-kind display of extremely rare computers. The museum features a dynamic presentation of the small start-up, founded in a garage by two young friends in 1976, that became the world's leading computer company. Guest speakers include renowned industrial designers and engineers who have played integral roles in computer history. Attendees will hear a first-hand account from industrial designer Jerry Manock, who created designs for the Apple II and III in the 70s and 80s. Vintage computer enthusiasts will enjoy a presentation from acclaimed computer engineer Bil Herd, creator of several noteworthy designs, including the Commodore 128. Computer Museum of America?s companion exhibit, ?LINK: Personal Computing >from Switches to Pockets,? features the links from the past to the present with displays of iconic computer brands including original computers like the IBM PC, as well as some very rare and unique machines such as the Kenbak-1. VCFSE is hosted and produced by the Atlanta Historical Computing Society and the Computer Museum of America. VCFSE is the premier vintage computer festival in the southeast and part of the VCF family of vintage computer festivals, which include VCF East in New Jersey, VCF Midwest in Chicago and VCF West in California. The VCF mission is to educate, promote and demonstrate the evolutionary significance of vintage computers, software and gaming to today?s new generation of innovators by offering attendees a chance to experience the technologies, people and remarkable stories that embody the history of the computer revolution. VCFSE 4.0 will be held at Kings Market Shopping Center, 1425 Market Blvd, Suite 200, Roswell, GA 30076, in what was previously a Comp-USA Super Store. The Festival is open from 10 AM to 7 PM on Saturday and from 10 AM to 5 PM on Sunday. Adult admission is $10 per day or $15 for a two-day pass. Children ages 17 and younger are admitted free when accompanied by a parent or guardian.

jrIDE sidecars: Interested in another chance?

by mbbrutman＠brutman.com

Short story: We are thinking of producing another set of 25 and want to know how much interest there is out there. If you are interested in purchasing one please email me. --- What is it? An IDE interface, clock/calendar, and a memory expansion sidecar for the PCjr. The BIOS extension allows booting from recent IDE/PATA hard drives that support LBA addressing mode. (Compact Flash with an adapter or Disk On Modules also work.) The memory expansion brings the machine from 128KB to 736KB. The last time we did this the price was around $75 for the kit of parts; you have to supply your own sidecar shell. See http://www.brutman.com/jrIDE/jrIDE.html for more details. Mike

QSIC update

> So here's a quick update on where Dave Bridgham and I are with the > QSIC ... We have the first of two wire-wrap prototype QBUS motherboards > more or less (see below) done .. the hardware is 'mostly' working; most > of the work from here on out will be FPGA, etc, programming. There > _are_ a few additional QBUS lines used for bus master (DMA) and > interrupts which we haven't used yet, and one of the first things done > now is to get those two kind of bus cycles working > ... > With that in hand, we can do the first controller (RK11), using memory > in the FPGA to simulate a small disk. Well, Dave has made a big step down that road; he has DMA working (both the bus arbitration cycle for DMA, as well as master-mode transfers to and from QBUS slave memory). He's now starting in on interrupt cycles; once those work, he effectively has emulation of a minimal small RK (he already has all the registers, since he needs them to control the DMA to and from the RAM disk). At that point I should be able to test it by making it the swap drive on a Unix V6 load. Noel

Big-Board II & Micro Cornucopia User Group Disks

by james.h.simpson＠gmail.com

Thanks very much to all who posted a reply. The BBII disk files was something I didn't have, and the CD image had some very interesting stuff. I did go and download the bitsaver files also. Thanks again!

Documentation on DEC's Omnibus Module M865 (Console Teletype Control)

by admin＠meiner.ch

Hi guys... I am currently looking for documentation (configuration, SCH, ...) on DEC's M865 Teletype-interface. Not the M8650 or M8655, mind you. Could someone point me to the right direction? Thanks a lot, Martin

Running RT11v4 on 11/03

by rich.cini＠verizon.net

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

by jnc＠mercury.lcs.mit.edu

> From: Mattis Lind > I have a physical tech manual (which is not the same as the one at > bitsavers) > ... > I should probably scan that tech manual if someone hasn't done it > already. 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.
