Hi, Does anyone happen to have a spare MXV11-B (M7195-XX) they would be willing to sell or trade? I'd like to build a small BSD2.11 system from this M8192 from the cheap board guy on e-bay and need something with a bootstrap ROM. Mark -- Mark G. Thomas (Mark at Misty.com), KC3DRE

RP06 drives are typically connected to 3-phase power, but only use two of the three phases. I have and RP06 running at home on 110/220VAC 2-phase. -- Michael Thompson

Announcing TCP/IP for RSX-11M-PLUS

by bqt＠softjar.se

I'm happy to announce a new release of TCP/IP for RSX-11M-PLUS. Since I'm broadening the scope of the announcement slightly, a more complete list of features is included, and not just what changed since last. For anyone who is currently running TCP/IP for RSX, I strongly encourage you to update to this latest version. Several improvements have gone in in the last couple of weeks. Most important change is that there now is telnet support, both client and server side. The TCP/IP for RSX that I've written is sometimes referred to as BQTCP/IP, just to make clear that it is a different product than Process Software's TCPWARE, or JSA's TCP/IP. BQTCP/IP is a rather feature rich TCP/IP implementation, which also comes with libraries for various high level languages. The API is not compatible, even at the source level, with Unix, but on the other hand, if people write some code, they will see that it is a very easy API to work with. The reasons for the incompatibilities are several, including both resource concerns and differences between how RSX works and Unix like operating systems. BQTCP/IP has tried to comply with all relevant RFCs, but I'm sure there are corners where it does not do things right. It also does not demand much resources. It do require RSX-11M-PLUS with split I/D space, and it has only been tested properly on RSX-11M-PLUS V4.6. It should work on any version 4 release of RSX-11M-PLUS, but there might be a couple of tweaks or fixes needed. BQTCP/IP is distributed in binary form, so very little compilation is required to get it up and running. However, pretty much all utilities do come with sources. The actual TCP/IP stack sources are not included. I do not have a good setup for distributing them in a sane way, and it has had a low priority on my list of things to do. But I do not mind distributing the sources as a general principle. All that said, BQTCP/IP current supports the following protocols: o Ethernet and loopback interfaces. o ARP. BQTCP/IP can use Ethernet in co-existance with DECnet, or standalone using the provided Unibus ethernet device driver. o IP. The largest IP packets supported are approximately 8KB. o ICMP. o UDP. The largest UDP packets supported are approximately 8KB. o TCP. The window is approximately 8KB in size, and TCP do manage out of order packets in an efficient way. BQTCP/IP supports the following applications: o DHCP. DHCP can be used to configure interface addresses, network masks, default gateways, DNS servers and NTP servers dynamically. o NTP. NTP can be used to set the local time. o TELNET. The TELNET server hooks in to the standard TT: terminal driver, and the number of terminals to create is configurable. The TELNET client can be used to connect to other systems. o FTP. The FTP server can serve all kind of files to other RSX systems, and can serve text and binary files to any system. The FTP client can retrieve RSX format files from RSX servers, and text, binary and block format files from any system. o TFTP. The TFTP server and client can be used for simpler file transfer operations. o RWHOD. RWHOD is a program that reports current users and uptime from RSX, for other systems to collect. o IRC. IRC is a program to communicate with other users around the world. o IRCBOT. IRCBOT is a small example robot program connecting to IRC and performing a service for IRC users. o PCL. PCL is a protocol for printing, used by HP (and other) printers over a network. The PCL implementation in BQTCP/IP appears as a print symbiont, which you can create a printer queue for. o WWW. WWW (or World Wide Web) is a service that can present hypertext information to clients. The WWW server in BQTCP/IP also supports CGI, which makes it possible to create dynamic content. o DNS. BQTCP/IP have DNS implemented as an ACP, that anyone can query to get translations between IP addresses and domain names. It also supports different users using different name servers, or private translations. o SINK. A standard TCP service. o ECHO. A standard TCP service. o DAYTIME. A standard TCP service. o QUOTD. A standard TCP service. o IDENTD. A standard TCP service. BQTCP/IP also have automatic IP spoof detection and prevention. Additional tools are IFCONFIG, PING, TRACEROUTE, NETSTAT as well as two new pages for RMD. High level language libraries exists for BASIC+2, PDP-11 C and FORTRAN-77. I'm sure I have forgotten a thing or three, but that's a fairly comprehensive list. The documentation is a weak point, but there is hopefully enough documentation to get people running, and I am happy to answer any questions, or give support if needed. BQTCP/IP is already running on the internet, and have been for a while. People who are curious to check it out can ether look at http://madame.update.uu.se/, or telnet to telnet://madame.update.uu.se and login as user GUEST with password GUEST, or use ftp against ftp://madame.update.uu.se. Anonymous ftp account exist. As usual, the distribution is available from: ftp://madame.update.uu.se/bqtcp.dsk ftp://madame.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The .tap file is an RSX virtual tape. It is only possible to download and use if you are using FTP from anther RSX system and fetch the file. The .dsk files are virtual RL02 images that are useful both from within RSX as well as through emulators. The documentation is also available through ftp on Madame, or also at http://madame.update.uu.se/tcpipdoc Johnny

Items to get rid of - North Haven CT 06473 area

by woyciesjes＠sbcglobal.net

I got a few items I need to get rid of: 2 HP LaserJet 5MP - One I know works. The other I had for parts, I think it works. I believe I have a PS module in it. There is also a RAM chip siting with it too, don't have the specs at the moment. Includes 3 toner carts, all in various states of used. HP JetDirect external printer server - LPT, RJ-45, BNC Black IBM Model M type keyboard with trackpoint. PS/2 mechanical keyboard with AT connector. Shipping is unfortunately something I can't do at this time. Monetary donation would be nice, but I just need these to go. Some good lager or ale wouldn't be turned down either... :) -- --- Dave Woyciesjes --- CompTIA A+ Certified IT Tech - http://certification.comptia.org/ --- HDI Certified Support Center Analyst - http://www.ThinkHDI.com/ Registered Linux user number 464583 "Computers have lots of memory but no imagination."

A tale of woe, including carelessness, stupidity and laziness....

I'm pretty blown away that the various grounds could be offset by that much, to produce that kind of current when they were tied together. Wow. Noel

Pre-VCFMW Sales and Free Stuff

by silent700＠gmail.com

It's a bit late but I may as well post my list of stuff I'd like to see go away this weekend. Small items can be delivered to you at VCF Midwest. Large items you'll have to pick up from my home or storage, both of which are <10 miles from the show, either during the week before or on Sunday evening after. (Or Monday mid-day if you're still in town.) The list at present: FREE (for pickup or +shipping) DEC TS05 9-track tape drive. Pertec interface, rail kit should be around here somewhere. Very clean, assumed working. DEC RL02 Drive. Once a home to mice, now a real "fixer-upper." Hey, they're tough drives. IBM MagStar MP 3570 tape library. Missing its tape cartridge but drive should be OK. SCSI interface. Heavy. FOR SALE Digital DECWriter III printing terminal. Repainted top, badge bent and poorly glued on. Was working when last tried. Cost is helping me get it out of the basement and another DECwriter down there to replace it. Digital DECWriter II printing terminal. Not sure about this one. Looks clean but untested. Will trade for something significantly smaller. I'll keep a running list here: http://chiclassiccomp.org/forsale.html If it's no longer on that list, it's gone.

ASR-33 differences

by cramcram＠gmail.com

Hi, I've finally gotten a hold of a restored ASR-33. One question I have concerns the paper tape reader. My recollection of using this TTY in the 70's was that the reader switch lever had 4 positions; on this tty there are 3. I know that for I have to add a reader control relay to interface to my PDP-8. So the question is: does having the 3 vs. 4 position reader lever affect using this with a PDP-8? Thanks, Marc

Larry Niven's Altair

by dave＠661.org

An Altair 8800 that once belonged to Larry Niven is up for auction. Larry Niven has long been a member of the Los Angeles Science Fantasy Society (www.lasfs.org). This group has existed since 1934 and was the starting point for many science fiction and fantasy authors. Larry Niven is one of them. This computer was purchased by him, but mainly used by his wife. In time, she got a newer computer and this one was made the club computer. It served in that capacity for many years until it too was replaced and was taken in by another club member who didn't want to see it parted out or thrown away. Fast-forward to 2008. I was contacted by that other club member to liquidate his collection. We went to Larry Niven's house whereupon he autographed this computer on the lid and the rear. I don't know if the drive unit was used by the Nivens with this computer, but it matches and is from the same collection. I also don't know where the client went. I haven't heard from him in years. You can see pictures in high resolution at https://www.flickr.com/photos/32548582 at N02/sets/72157653950476154/with/19938469936/ The auction is here (will be live July 25 at 3pm pacific) http://www.ebay.com/itm/231632418798 -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text.

Many Manuals - Also Boxes of Fan Fold Paper

by jhfinedp3k＠compsys.to

Since the topic of hard copy manuals is at least on a few minds, I thought I would mention that I have at least 20 feet of mostly DEC PDP-11 related manuals which will have to be tossed if a home can't be found. While I estimate that at least 90% of the DEC manuals are on bitsavers, some individuals may still wish to have hard copy manuals. Most of the manuals are either RT-11 software for many versions or manuals for specific hardware modules with regard to usage. There are no print sets. If you want a hard copy set of RT-11 Docs for V05.07 or TSX-Plus for V6.5, then you could reserve them for when I no longer will need them! Since I just turned 77, the wait might not be that long. I also have over 6 boxes of Fan Fold Paper (with sprocket holes), mostly 8 1/2" x 11", but maybe some 9 1/2" x 11" with tear off. The paper is available immediately. I will probably hold the manuals for at least 6 to 12 months. But I can't see anyone else bothering and it would all be tossed immediately. There is also PDP-11 Qbus hardware, but that is another matter. I am in Toronto, Ontario. Pickup ONLY since this stuff is much too heavy to ship! Jerome Fine
